Thank you for pointing the discrepancy to me. Please check if the corrected structural formula is what it should be. --Shaddack 06:44, 18 April 2007 (UTC)

Zn acetate
Here's the file from commons Image:BasicZnAcetate.png. Let me know if this does not work. --Smokefoot 02:26, 26 June 2007 (UTC)

TCS Toxicology and Chemical Substances
Can you redo the TCS Toxicology and Chemical Substances article as it was........ The TCS/ECB Administrator. —Preceding unsigned comment added by 139.191.136.150 (talk • contribs) --Leyo 11:39, 9 October 2007 (UTC)
 * I did not do anything in that article. Please address yourself to the right user. There is already an article on the same topic on European Chemicals Bureau, but there is no use to have two articles. --Leyo 11:39, 9 October 2007 (UTC)

Ok leyo you are quite right of the use of 2 articles but the new name of the European Chemicals Bureau is TCS (Toxicology and Chemical Substances), it's for this reason that we said TCS is known also as ECB.... And we need this article as TCS also for our Stakeholders. So I do not know who has deleted the TCS article, but before doing so, it must be the right way to ask the creator/owner of the article. Thanks. —Preceding unsigned comment added by 139.191.136.154 (talk • contribs) --Leyo 18:33, 9 October 2007 (UTC)


 * There should only be 1 article on TCS/ECB. The article can be named either
 * Toxicology and Chemical Substances or
 * European Chemicals Bureau
 * A redirect linking to the article can be created from the other name. Such a redirect was created by that edit. Links can also be added to TCS. Where can I find a record proving that "European Chemicals Bureau" has been renamed to "Toxicology and Chemical Substances"? There is no message concerning the new name on http://ecb.jrc.it/whatsnew. However in the top left corner of the website, both names are displayed at the moment. --Leyo 18:33, 9 October 2007 (UTC)
 * PS. Please tell me, where I can find the information about the new name of ECB. Then, we can decide what to do. Thanks. --Leyo 19:29, 9 October 2007 (UTC)

Hi leyo,

You are right there should be just one article for the same subject.

You can find TCS descripttion on the IHCP web sie at http://ihcp.jrc.ec.europa.eu/ (TCS is part of the IHCP which is part to JRC which is part to the European Commission).

You can find contacts on the Home Page of the TCS-ECB, please right to Dr. R. Allanou is also managing IT communication. Infact ECB is changing because of the new agency ECHA (European CHemicals Agency) located at Helsinki. For that reason ECB is called now TCS.

But as you, most of people know more ECB than TCS, what is normal.

139.191.136.150 08:57, 12 October 2007 (UTC)


 * OK. I have now moved the existing article European Chemicals Bureau to Toxicology and Chemical Substances (I have chosen to move European Chemicals Bureau to that place, because this article is older than the article TCS Toxicology and Chemical Substances). Please copy the content from TCS Toxicology and Chemical Substances you like to add and paste it into European Chemicals Bureau. It has to be done like this, because of the copyright: If I would copy the text from TCS Toxicology and Chemical Substances and paste it into Toxicology and Chemical Substances, it would look in the history as I had written the text by myself.
 * I would be glad, if you could do it that way. Thank you! --Leyo 11:20, 12 October 2007 (UTC)

Dear Leyo,

I introduce myself I am the Administrator of the TCS-ECB, so what we did is to merge the contents of the 2 articles.

Please have a look on the Toxicology and Chemical Substances Article you created. When you agree, we need I guess just to redirect TCS_bla-bla to that one. Because we publish to our Stakeholders under the name TCS_bla-bla, so we must keep that one. Thanks. 139.191.90.61 09:23, 17 October 2007 (UTC)


 * Yes, that's what I suggested. Thank you. I have now created the redirect from TCS Toxicology and Chemical Substances to Toxicology and Chemical Substances. I have standardized the formatting in the article. --Leyo 11:13, 17 October 2007 (UTC)

IA-Mass
Bonjour,

IA-Mass est le fruit d'une cooperation franco japonaise!

en japonais le mot IAMS est utilisé, en francais ou en anglais, IAMS est le nom d'une marque de pet-food pas tres recommendable, à voir toutes les petition qu'on vous demande de signer !

donc en francais et en anglais on utilise le vocable IA-Mass.

La methode et l'instrument sont le fruit d'un certain nombre de chercheurs dont le prof Fujii (Tsukuba Univ) et le doct Sablier (Ecole Polytechnique)..... et de quelques brevets....

Les applications sur lesquelles nous travaillons sont proches de l'environnement et plus particulierement sur le controle dans la filliere des plastiques en amont sur les matières premières et en aval sur les matières recyclées.

Merci —Preceding unsigned comment added by Maseracing (talk • contribs) 18:08, 26 October 2007 (UTC)


 * Bonjour. Je n'ai pas vu ta message plus tôt. C'est bien que tu as répondu sur la page Talk:Ion attached mass spectrometry. --Leyo 22:07, 28 October 2007 (UTC)

Edit Request
Hey leyo, i read over the Hard water article you requested to be copyedited. Just wondering if you wanna read it over again and tell me what i missed, i would appreciate it. Again only if you want to. {*TEE DUB*} (talk) 18:20, 6 December 2007 (UTC)
 * Hi Bombard. I think the article has improved quite a lot since September 2007, particularly in some sections. --Leyo (talk) 18:36, 6 December 2007 (UTC)
 * Ok good stuff, i just changed a couple areas of wording so that people dont have to use a dictionary to read it, lol {*TEE DUB*} (talk) 20:05, 6 December 2007 (UTC)
 * I'm not talking about your edit alone, but about all edits since September 28. --Leyo 21:18, 6 December 2007 (UTC)
 * I know, i was in no way whatsoever trying to take the thunder:) —Preceding unsigned comment added by King Bombard (talk • contribs) 17:39, 7 December 2007 (UTC)

Waiau/Hanmer
Hi Leyo - unfortunately I don't know that part of the country well enough to be abe to say which is right (I do live in the South Island, but at the other end of it, in Dunedin). I've left a note on the New Zealand Wikipedians' notice board - hopefully someone there will be able to clarify things. Grutness...wha?  00:51, 1 February 2008 (UTC)

Didanosine structure
Forgive the complete chemical ignorance here, but could you confirm that the structure that you've just added is the same as the original one? The position of the hydrogen in the pyrimidine ring is different from the original and from all versions I've found. Espresso Addict (talk) 00:41, 21 March 2008 (UTC)
 * IMHO these structures are tautomers of substituted purines. The structure I added is similar to the one in PubChem (linked in the article). You may also wish to ask the uploader of the image (he speaks English well enough). --Leyo 01:40, 21 March 2008 (UTC)

Structures to be replaced
Sure, I could take some of these. I know that a few (such as mifepristone and aprepitant) have already been replaced, so I'll go over the list and see which ones actually still need substitutes. Best wishes, Fvasconcellos (t·c) 17:07, 8 April 2008 (UTC)

Rollback
I have added the rollback feature to your user account, and to those other trusted Wikipedia chemists. I hope this helps with reverting any vandalism or other inappropriate edits you come across. (If you do not want rollback, just let me know, and I'll remove it.) -- Ed (Edgar181) 18:26, 21 April 2008 (UTC)
 * Thanks. This function seems to be quite similar to "revert" with popups. --Leyo 21:43, 21 April 2008 (UTC)

Cidofovir
''Hi Mykhal. Can you please move your structural formula to Commons or upload even an SVG version? Thanks. --Leyo 22:22, 23 April 2008 (UTC)''
 * OK, let me see.. could you point me to some info on moving images to Commons ? Mykhal (talk) 00:57, 7 May 2008 (UTC)
 * Replied at user's talk page. --Leyo 17:19, 7 May 2008 (UTC)

Nonsense redirects
You tagged some pesticide and herbicide redirects such as Prallethrin for deletion. I changed them to stub articles. --Eastmain (talk) 20:13, 8 May 2008 (UTC)
 * Thanks. I added interwikis to those articles, where I could find any. You might wish to add some information, references or the structural formula from these articles here. --Leyo 23:54, 8 May 2008 (UTC)

Drugbox
✅ Done :) Fvasconcellos (t·c) 16:32, 6 August 2008 (UTC)
 * Thanks. BTW: I changed your user rights on de-WP to “Editor”. --Leyo 16:45, 6 August 2008 (UTC)
 * Hey, thanks! I guess I should learn German ;) Fvasconcellos (t·c) 21:57, 6 August 2008 (UTC)

Adminship
I just wanted to let you know that I have taken your suggestion and nominated myself for adminship on Commons. -- Ed (Edgar181) 19:14, 13 August 2008 (UTC)
 * Thanks for notice. I would have seen it anyway as I added this page (that was empty at that time) to my watchlist. Good luck! --Leyo 20:17, 13 August 2008 (UTC)

Endo/Exo
Hey there, what do you think of my image? --Rifleman 82 (talk) 18:04, 20 August 2008 (UTC)
 * Thanks. It looks much better than the perviously existing version, which could be deleted IMHO. However, it's a pitty, if such images that can also be used in other Wikipedias (e.g. no English text) are not uploaded to Commons. --Leyo 18:20, 20 August 2008 (UTC)
 * I always find bicyclics hard to draw... Are the terms "endo" and "exo" used in other languages? If they are used in at least a *few* languages, I am all for moving to commons. --Rifleman 82 (talk) 18:26, 20 August 2008 (UTC)
 * “endo” and “exo” are Greek prefixes that are used in many languages. --Leyo 18:57, 20 August 2008 (UTC)

Chemistry dispute templates
Debate has been Relisted. --WoohookittyWoohoo! 00:16, 20 September 2008 (UTC)

 * (We don't use ambox in imagespace. We use imbox. ViperSnake151 19:01, 23 September 2008 (UTC)
 * I was not talking about “ambox” or “imbox”, but on the text and the image you removed. --Leyo 20:47, 23 September 2008 (UTC)

PFOA
Leyo, can you weigh in on the PFOA issues of neutrality? I am frustrated right now from a lack of discussion in general, and especially on specifics (sentences, citations, etc.) I think you could help add perspective. -Shootbamboo (talk) 22:36, 13 October 2008 (UTC)
 * I added a few comments (what I also would have done without your notice). --Leyo 16:11, 14 October 2008 (UTC)
 * I apologize if my notice irked you. I just saw your reply. I am not good at going back to talk pages yet I just learned about watch lists. Do you have any suggestions for improving the PFOA article? I realized today I had over-wikified the article and I have started to remove those. Thanks -Shootbamboo (talk) 04:45, 3 November 2008 (UTC)

AIV
When you report users to AIV, ensure they've received a full set of warnings and edited after the final warning, which must be recent. In the case of your report this afternoon, the user had no actual warnings. Also, you put on AIV that the user had been blocked on Commons. Upon checking, he does not appear to be blocked there, or even warned with the exception of some informal notices about HTML use and such. If you have questions, let me know on my talk page. لenna vecia  17:37, 14 October 2008 (UTC)
 * I judged an emergency block to be most important to ommit further vandalism. The user was quite fast in creating talk pages and new sections on existing ones. So my main goal was to prevent work to undo all that vandalism. The user was blocked on Commons for the same reason (log) and I've warned him on his user discussion (without template). He removed that again. BTW: Can you also delete Template_talk:!-/doc? --Leyo 17:47, 14 October 2008 (UTC)
 * Deleted. Thanks for the details. Hopefully he'll stop now. لenna  vecia  17:51, 14 October 2008 (UTC)

Fluorocarbon
I have hesitated to ask for your assistance, but there is a lot of discussion about the definition of fluorocarbon on the that talk page. My attempt to diffuse the matter has nearly led to an edit war on (organofluorine). Could you weigh in on the fluorocarbon talk page? Thanks. -Shootbamboo (talk) 23:27, 8 November 2008 (UTC)
 * Looks like the potential for an edit war has been averted. There is still a discord of opinion on the definition of fluorocarbon. Thanks. -Shootbamboo (talk) 00:11, 9 November 2008 (UTC)

C-F bond
I think the quality of the carbon-fluorine bond page would be greatly improved with an image that shows a C-F with the delta negative sign over the fluorine and the delta positive sign over the carbon. How could I go about doing this? Thanks. -Shootbamboo (talk) 02:34, 16 November 2008 (UTC)
 * I'm not sure if I understand what you mean. If you want to get such an image drawn, you might list it on WikiProject Chemistry/Image Request or you go and ask e.g. Benjah-bmm27 directly. --Leyo 23:48, 16 November 2008 (UTC) PS. This paper might be of interest concerning the properties of polyfluorinated substances.
 * thanks for the citation. you answered my question. i was wondering if there was a place for us to learn to do it ourselves (draw chemical structures on wikipedia), but i will ask benja-bmm27 thanks. -Shootbamboo (talk) 05:12, 18 November 2008 (UTC)
 * See also WP:CSDG. --Leyo 08:57, 18 November 2008 (UTC)

HBCD
Thank you very much for your contribution to Hexabromocyclododecane. I guess you accidentally removed the link to ECHA between the external links. Please note that was very important to try to balance the BSEF source as is not neutral at all due to the fact is the panel of producers. Please note that ECHA is a EU governmental source in which a lot of official information can be found. Thank you very much in advance for your understanding.--Avogadro-I (talk) 21:52, 1 December 2008 (UTC)
 * Hi Avogardo-I. No, that wasn't an accident. There shouldn't be an external link to the ECHA homepage (if the specific page there is not on HBCD). Please not that I added a wikilink to European Chemicals Agency instead. --Leyo 22:16, 1 December 2008 (UTC)

pt:Cadeia carbônica
Everything seems to be in order. I'm not as familiar with the policies and guidelines of pt-WP as I am with ours, but merges don't need to be listed anywhere—the template suffices. Merry Christmas, by the way (Fröhliche Weihnachten? :) Fvasconcellos (t·c) 00:30, 23 December 2008 (UTC)
 * Thanks for the reply. I wish the same to you (yes, it's correct). --Leyo 02:30, 23 December 2008 (UTC)

Orphaned images tool
Hi Leyo,

It can be done. Here's an example I whipped up for DE wiki.

I haven't decided if I would want to do a page for each language, or link Orphaned images to an i18n file and let the user choose the wiki from a dropdown.

Besides translation, there is one issue: I filter out articles that have already been tagged for deletion - for example, IfD and di-orphaned fair use. I wouldn't know how to find the equivalents for a given wiki. Not crucial for the tool to work, but I've found it helpful. Let me know what you think, and maybe I could make the orphaned_images_de.php page permanent. -- Ja Ga  talk 19:54, 2 February 2009 (UTC)
 * Great. I think both options would be fine. Concerning the filter: You are right, it might be too difficult to find the equivalents for a large number of wikis. In the case of de-WP, I think your tool would be useful without that feature. Please let me know, if you would like me to provide a German translation. --Leyo 21:12, 2 February 2009 (UTC)
 * I would very much appreciate a German translation. :) If you don't mind, I'd like:
 * A new file name (a German replacement for "orphaned_images_de.php")
 * A translation of the text in orphaned_images_de.php
 * A translation of the "See also" section, like the one in Category:Other images that should be in SVG format
 * A translation of "adding orphaned images link" for my edit summaries in de-wiki
 * With, of course, full license to you to word things however you think is best. Thanks! -- Ja Ga  talk 23:26, 2 February 2009 (UTC)
 * OK, I will give a try:
 * “Verwaiste_Bilder.php” (or “Dateien” for “files”)
 * Verwaiste Bilder in einer bestimmten Kategorie

Dieses Tool gibt diejenigen Bilder in der Kategorie aus, die in keinem Wikipedia-Artikel eingebunden sind. Die Einbindung in Seiten anderer Namensräume (Diskussionsseiten, Benutzerseiten, usw.) wird dabei nicht berücksichtigt. (skipped sentence concerning deletion templates)

In der zweiten Spalte wird der Uploader angezeigt. Dort sind jeweils diejenigen Beträge des betreffenden Benutzers verlinkt, welche dieser direkt nach dem Hochladen des betreffenden Bildes gemacht hat. Anhand dieser Benutzerbeiträge kann oft nachvollzogen werden, für welchen Artikel ein Bild ursprünglich gedacht war. Auf diese Weise kann geprüft werden, ob ein Bild durch ein besseres ersetzt worden ist. In der Benutzerbeitragsliste ist das entsprechende Bild ganz unten aufgeführt, darüber stehen die nachfolgenden Beiträge.

Gib die zu überprüfende Kategorie an (case sensitive) Verwaiste Bilder in der Kategorie:name (I think the second part is not necessary)
 * Siehe auch
 * Something like “+Tool zur Auffindung von verwaisten Bildern”
 * --Leyo 01:23, 3 February 2009 (UTC)

Hey, Leyo, thanks for the translation. Here's what I have so far. But I forgot some of the other messages: That should be it. Thanks for all your help!! -- Ja Ga  talk 04:39, 3 February 2009 (UTC)

When I say "Hosted on Commons", I mean "this image is in your category but it is actually located on Commons". You can see it, for example, here. Thanks,  Ja Ga  talk 23:41, 3 February 2009 (UTC)
 * OK, but this case should not occur very often on de-WP as local descriptions pages of Commons images are deleted. Of course, this is no reason of not including that feature in the German version. So, I would suggest to translate it like this:
 * Lokale Bildbeschreibungsseite eines Commons-Bildes
 * or if this is too long
 * Bild liegt auf Commons
 * --Leyo 23:50, 3 February 2009 (UTC)

OK, I think it's done. If it looks OK to you, I'll put it in the SVG Chemie page. -- Ja Ga  talk 03:56, 4 February 2009 (UTC)
 * Except - is there a translation for "case sensitive"? -- Ja Ga  talk 03:58, 4 February 2009 (UTC)
 * I don't know any (see also article in de-WP). Sorry, I have already added it to the mentioned page. I think your tool should also be added to this tool overview page. And what about adding it to Tools? --Leyo 09:31, 4 February 2009 (UTC)
 * You may add links for switching between the different language version of for tool. What about versions for additional Wikipedias? At the beginning, the text could be in English. You could ask users for providing a translation in their own language. Maybe you could use something like this (view example) as an interface for the translation. --Leyo 15:58, 4 February 2009 (UTC)
 * Hey Leyo, sorry I lost track of everything - got a lot of irons in the fire these days. I'd say you're right about the tool lists. (Could you put it on the German list for me? I wouldn't know how to explain it.) I also like your different language suggestion - I'll try to figure it out when I've got the time. -- Ja Ga  talk  03:13, 12 February 2009 (UTC)
 * OK, I added it to the de-WP tools list. --Leyo 23:19, 12 February 2009 (UTC)
 * Thanks! -- Ja Ga  talk 03:26, 13 February 2009 (UTC)

Pharmacology categorization

polyamide-imide page
I saw that you made an edit to the page but being new to Wikipedia, was not able to see exactly what you changed. I don't know what your interest in amide-imides is, but this page has been greatly modified from where I left it about 2 years ago. My company make polyamide-imide in powder and pellet forms only. So any comments I make about solution products need to checked. I plan to enrich the content on the pelletized products for extrusion and injection-molding and if you already have some content I'd be happy to review it.George Cekis (talk) 13:47, 15 April 2009 (UTC)

JPEGs by Materialscientist
Thanks for the note. As a photographer, I do understand jpeg compression problems, but. I've tried several times to upload PNG and SVG (just picked up from uploads, File:BariteWorldProductionUSGS.PNG and File:BariteWorldProductionUSGS.JPG. My PNGs never show up in thumbs (i.e. in articles; I see something like a framed symbol |). I could really use an advice on that. So far, everyone thought I simply don't understand JPEG/PNG difference. Materialscientist (talk) 23:09, 3 July 2009 (UTC)
 * Mysteriously, File:BariteWorldProductionUSGS.PNG is fine now as a thumb. Maybe there is a delay after file upload, or something has been fixed. I tried several PNGs in the past, and none worked after upload (though was fine in full width on WP). Sorry for confusing writing. Materialscientist (talk) 04:55, 4 July 2009 (UTC)
 * Sorry for my delayed reply. It is difficult to find out what was the problem as it does not exist anymore. Please upload your structure drawings as PNGs in future. If the problem re-occurs, please let me know and I will try to find out what is the reason.
 * BTW: Have you ever thought about uploading your files to Commons instead of to en-WP? Like that they could also be used in any wikiproject. --Leyo 14:58, 8 July 2009 (UTC)
 * I usually upload to WP first, because there is much better communication if images have problems (forgot copyright, and someone wants to speedy delete them, etc.), and then move to commons. One reason I stopped using commons for some time was also my username change (which was not that smooth at commons). Regarding PNG - the problem does persist. I tried again with File:Cr3C2structure.png and it is still the same thing - Ok in full view and invisible in thumb. I admit I use (have to) a very old program to create my structures, but I convert them with another one. Maybe that old program does something wrong, and conversion does not fix that. Materialscientist (talk) 22:49, 8 July 2009 (UTC)
 * I don't know meself, but I posed the question here. --Leyo 08:00, 17 July 2009 (UTC)


 * Your program does generate invalid files, they are missing the IEND chunk. See Graphic Lab/Image workshop/Archive/Jul 2009. Atleast "Save as..." from GIMP seems to fix the files. --Petteri Aimonen (talk) 19:00, 19 July 2009 (UTC)

 * BTW: Can you check the bottom (JPG) structure in NK1 receptor antagonist? Are there really two charges? --Leyo 20:04, 21 August 2009 (UTC)
 * No way, those "S"s should just be stereochemistry descriptors, not sulfur atoms. See . You can use the GR-205171 "framework" (orientation, etc.) for this one. Fvasconcellos (t·c) 20:33, 21 August 2009 (UTC)
 * And for CP-99994, you can just remove the aminotetrazolyl group from the GR-205171 structure. Fvasconcellos (t·c) 20:35, 21 August 2009 (UTC)

de:Hofmann-Umlagerung
Hi Leyo

Sorry to trouble you, but you're one of the few de-wp editors I know.

There is an error in this sentence:

"Brom kann durch andere Reagenzien, wie Chlor Cl2, N-Bromosuccinimid (NBS) oder 1,8-Diazabicyclo[5.4.0]undec-7-en  (DBU) ersetzt werden."

I think this sentence is trying to say that you can use chlorine, NBS, or DBU as an alternative to bromine. I think that is incorrect in that the reaction scheme shows NBS and DBU are being used together. Perhaps it should be phrased

"Brom kann durch andere Reagenzien, wie Chlor Cl2 oder N-Bromosuccinimid (NBS) und 1,8-Diazabicyclo[5.4.0]undec-7-en  (DBU) ersetzt werden."

I'm not sufficiently fluent that I would make the change, and I don't monitor the de-wp Watchlist in case there any problems. Perhaps you can take a look? --Rifleman 82 (talk) 01:05, 20 March 2010 (UTC)
 * Hi Rifleman. Thanks for dropping me a note. As I am not familiar with the Hofmann rearrangement, I put your question in the de-WP WikiProject Chemistry. The so called “Redaktion Chemie” is quite active. Hence, there will be a reply soon. --Leyo 10:11, 20 March 2010 (UTC)

About Nkufo
Hi there Leyo. Do you know, why the article name has been changed back to Blaise Kufo? In Dutch media, and on Twente's official website, there stands that his name is Blaise Nkufo.

Anyways - thanks for the link ;). @ Bocanegra 18:02, 12 April 2010 (UTC+1)
 * It's a mess with all the different spelling versions of his name in media. I hope we can clarify this at Wikipedia talk:WikiProject Football. --Leyo 16:08, 12 April 2010 (UTC)

DDT pic
Hi Leyo, Thanks for adding the pic to DDT showing DDT's transformations. I'd thought the article needed something like that for a while, but I don't have chemdraw so I couldn't do it. One thing though: It shows H2 over the arrow for the DDT to DDD transformation--and maybe that's how you'd affect that reaction in the lab--but in the environment (which is the topic of the that section) there isn't H2 floating around. I wonder it you might able to fix that. The WHO (here) shows -Cl- + H+ over the arrow, which obviously isn't balanced, but probably more accurately reflects what happens in nature. Also, it would be great if you could label the molecules. Thanks. Yilloslime T C  15:07, 12 May 2010 (UTC)
 * Hi Yilloslime. I was unsure, whether to take  or  . In the literature, I found many examples of reductive dehalogenation for the first option. If you like, I can draw and upload an alternative version with the second option.
 * I changed the description in a way I think labels in the image itself are not necessary. --Leyo 15:38, 12 May 2010 (UTC)
 * I think it would be better to use . The sources you linked don't actually give DDT → DDD as a specific example, while the WHO does, and it shows it as  . And--I'm no biochemist--but it seems highly unlikely to me that the reducing agent in a biological system would be H2 rather than some equivalent like NADH or 2RSH → RSSR or something like that. Yilloslime T C  05:27, 13 May 2010 (UTC)
 * IMHO it is just important that they show reductive dehalogenation. It does not matter so much which substance it actually is. It seems to be more a matter of taste to me. I just uploaded the alternative versions as you requested. --Leyo 01:25, 15 May 2010 (UTC)

Speedy deletion
I noticed that you tagged the page File:Microsoft.svg for speedy deletion with the reason "not a real .svg file". However, "not a real .svg file" is not currently one of our criteria for speedy deletion, so I have removed the speedy deletion tag. You can use WP:FFD if you still want the page to be deleted. Thanks! Stifle (talk) 12:53, 14 June 2010 (UTC)
 * You can select whatever reason you want such as NowCommons (File:Microsoft wordmark.svg is the same logo, but with real vector data). It is a technically bad and unused file. --Leyo 13:17, 14 June 2010 (UTC)

tech help
Hey mate, i uploaded this image to be used on wikipedia, however im not sure about the tag, the owner released it for use on all websites to promote pages. Could you check it please and maybe fix the tag if it's wrong. Eli +  05:57, 6 July 2010 (UTC)
 * Have a look at Commons:Category:Facebook. IMHO it could be licensed like the other logos in this category since text-only logos are ineligible for copyright. Another option would be to tag it with Non-free logo. --Leyo 08:25, 6 July 2010 (UTC)

Request for assistance
Hi Leyo, I know you do some work with chemical structures, which I am hoping includes crystal structure data. I recently got the article Hans Freeman to GA standard, and am considering a run for FA. Freeman's PhD work included the crystal structure of biuret hydrate (completing most calculations by hand!), and I think an illustration based on the Acta Cryst structure would be a nice addition. Would you be able to provide a suitable image? Alternatively, can you suggest someone else who would be better suited to help? Thanks. EdChem (talk) 16:24, 21 November 2010 (UTC)
 * Hi EdChem. I am sorry, but my work here does not include crystal structure data. Benjah-bmm27, Materialscientist or Orci might be able to help. You might also consider adding your wish to WikiProject Chemistry/Image Request. --Leyo 20:46, 21 November 2010 (UTC)

CSD F8 FYI
WP:CSD excludes deletion of files in a different file format:. There are some valid reasons for that; you'll note commons outright refuses to delete files of different formats. Magog the Ogre (talk) 17:16, 21 December 2010 (UTC)

I imagine it did, but commons is weird like that they like multiple formats. I'm thinking FFD or just moving it to commons may have been a better solution. I'll probably do it myself (I'm a bit OCD that way, please forgive me). Magog the Ogre (talk) 17:27, 21 December 2010 (UTC)

Asking for the permission to use the photos in the article
18 Feb 2011

Dear Leyo,

I'm a year 2 student studying Chemistry in the University of Hong Kong. I'm writing a journal article about the common acne-treating ingredients and I would like to ask for the permission to use the photos in the following article.

The permission letter is required during submission of the article. Look forward to your kind reply of this message. Thank you in advance for your generous permission and attention.

Yours sincerely,

Tantalum pentoxide
Hi Leyo, last year you have added an image of U3O8 crystal structure to this article with a comment "crystal structure is similar". Today in pl: and en:wikis a question appeared about this image and I wonder if you have a reference confirming correctness of such its usage. Regards, Michał Sobkowski (talk) 13:26, 1 June 2011 (UTC)
 * See this edit by the creator of the image. For more information, please refer to him. --Leyo 13:34, 1 June 2011 (UTC)

Category:Unclassified Chemical Structures
Nice addition of the orphan file link - I wondered if that was possible. Anyway, it's 2am, and time for bed. I'll add the rest tomorrow - ~2000 more and AWB can only do 33 per minute even with the enter key wedged down...  Ron h jones (Talk) 00:52, 9 June 2011 (UTC)
 * So we will soon have all such files in a single category. Unfortunately, it is quite inefficient to nominate hundreds of them individually for deletion (e.g. like here). It would be neat to simplify the procedure. --Leyo 08:30, 9 June 2011 (UTC)
 * Agree. Once I have removed the wanted ones, and left all the orphaned files of no value, then I think we could post a notice on the Chemistry Wikproject page to ask editors to view the list and comment (and have their comments all together, on the Category talk page). After a short time we can ask at WP:FfD, how they would like the deletion done.  Ron h jones  (Talk) 11:56, 9 June 2011 (UTC)
 * All done, now 4042 in the category. I have a text list at User:Ronhjones/Unclassified Chemical Structures. My plan is...
 * Get a text list out of the orphan file link you added (we have to wait 24h for the update)
 * Get both text lists in MS Access, and compare to give a 3rd list of the non-orphan files.
 * Run this 3rd list through AWB to change that category and tag for move to commons.
 * Move those files to commons - that will take a while!
 * What is left in the Unclassified Chemical Structures - we propose for deletion.
 *  Ron h jones (Talk) 20:04, 9 June 2011 (UTC)
 * Concerning step 3: I suggest adding a specific category (“Chemical Structures to be Moved to Commons” or similar) and not just adding mtc.
 * Poor quality images should not moved to Commons by no means. Instead, the should be tagged by chemical. --Leyo 12:11, 10 June 2011 (UTC)
 * 1, 2, and 3 done - Category:Classified Chemical Structures has the non orphan structures, and Category:Unclassified Chemical Structures is now left with all the orphans.  Ron h jones (Talk)
 * No.5 - posted notice on Wikipedia_talk:WikiProject_Chemistry, and link to Category talk:Unclassified Chemical Structures  Ron h jones (Talk) 23:19, 10 June 2011 (UTC)

The article European chemical Substances Information System has been proposed for deletion&#32; because of the following concern:
 * No independent sources, does not meet WP:GNG.

While all contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion. Crusio (talk) 21:10, 23 October 2011 (UTC)

Nomination of European chemical Substances Information System for deletion
A discussion is taking place as to whether the article European chemical Substances Information System is suitable for inclusion in Wikipedia according to Wikipedia's policies and guidelines or whether it should be deleted.

The article will be discussed at Articles for deletion/European chemical Substances Information System until a consensus is reached, and anyone is welcome to contribute to the discussion.

Question about a German image
It says that you are an admin on German Wikipedia, so maybe you can help. It says that File:250px-Bischofszell.jpg comes from German Wikipedia. The deletion log tells that de:Datei:Bischofszell.jpg, which is likely the same image, was moved to Commons, but the file name on Commons isn't available. Are you able to find the file name on Commons by looking at the deleted file information page? --Stefan2 (talk) 14:24, 28 February 2012 (UTC)
 * It is indeed the same picture, but it does not seem to be on Commons. I asked the admin who deleted the local version. --Leyo 15:06, 28 February 2012 (UTC) PS. What about replying my question on your talk page? ;-)
 * Good. I found a user who had copied a lot of files from German Wikipedia. I was able to tag most images with NowCommons, report some files for deletion and add interwiki links to a few files still on German Wikipedia, but I wasn't able to find this one. --Stefan2 (talk) 00:28, 1 March 2012 (UTC)
 * I restored the image locally and moved it to Commons. Are you talking about this user? --Leyo 10:10, 2 March 2012 (UTC)
 * Yes, that's the one. Only three images left now and that is because they are still on German Wikipedia. Unfortunately, one of them has no source and the other two ones are bsr which may mean problems with Commons:COM:COA. --Stefan2 (talk) 00:33, 23 March 2012 (UTC)

Non-free images at the GL
I appreciate the vector versions are on Commons, but the non-vectors are marked as non-free on Wikipedia, so cannot be displayed on this page. The formatting is hardly ideal, but this is a minor concern in comparison to the copyright one. I hope this is clear, but I'm happy to discuss the matter further if necessary.  Nik Naks  talk - gallery 20:08, 7 May 2012 (UTC)
 * First you [//en.wikipedia.org/w/index.php?title=Wikipedia:Graphic_Lab/Illustration_workshop&diff=prev&oldid=491241578 vandalize] and then you discuss? What kind of attitude is this? These two logos are eligible to be moved to Commons and not non-free. --Leyo 23:36, 7 May 2012 (UTC)
 * Accusing me of vandalism is inappropriate, as you know. However, if you visit the three logos in question (File:Uis_logo_trans.png, File:HWL_MID_lock_up_E-R.jpg, File:Small_saicblue.png), they are all marked as copyrighted.  Whether or not these logos are truly simple enough to be on Commons is not something I can comment on, not being an expert, but nonetheless we should not simply ignore the tags while they remain here on Wikipedia.   Nik Naks  talk - gallery 06:42, 8 May 2012 (UTC)
 * Not an expert, but also not giving a damn about the assessment of a local and Commons admin? --Leyo 02:42, 9 May 2012 (UTC)
 * If an admin wants to change the status of the file on Wikipedia, then by all means remove the tag. As it stands, those three are copyrighted logos on Wikipedia, so cannot be displayed.  I am simply following policy to the letter.  I do not understand how my actions have caused so much distress.   Nik Naks  talk - gallery 06:48, 9 May 2012 (UTC)

When you look at the WP talk page you will see that there is a structure for Birds for identification, which has been established for a long time. There is no need for the images to be visible.

Scale rows in Chironius laurenti
Hey, since you have access to the paper can you confirm the "2 to 10 scale rows in males and 2 to 6 in females" description of Chironius laurenti by Reptilebase in Dixon et al.? It seems to be contradictory to the 12 scale rows midbody maximum also mentioned. I have a suspicion it refers to a specific part of the body, perhaps the head or tail, or perhaps it's an average.

Also as an aside, I discovered a description of C. laurenti before it was described by Dixon et al. in "The Snake Assemblage of the Pantanal at Poconé, Western Brazil: Faunal Composition and Ecological Summary (Strussmann & Sazima, 1993)". The authors were similarly unable to identify it as it was as of yet, an unknown species. -- O BSIDIAN  †  S OUL  18:22, 24 August 2012 (UTC)


 * Yes, it says that on page 142 (section Diagnosis). It also says that C. laurenti is the only Chironius species with a combination of 12 scale rows at midbody, divided anal plate, 163–181 ventrals, 32–36 maxillary teeth […] --Leyo 18:46, 24 August 2012 (UTC)

File:Hmd-reaction.PNG
Got an opinion about this? A different image exists under the same name on Commons, but if I've understood things correctly, both files are supposed to show the same thing. However, both the English and the Japanese articles contain lots of chemical terms which say very little to me; it's possible I've misunderstood something. Since the images are a bit different, does it mean that one of them is wrong, or do they show two different valid representations of the same thing? Also, do we really need both images? Ideally, the files would, of course, be in SVG format instead of PNG. --Stefan2 (talk) 13:08, 13 October 2012 (UTC)
 * Both show the same thing and are of low quality. I suggest to bring the issue to Wikipedia talk:WikiProject Chemistry, because enzyme reactions is not my topic. --Leyo 13:22, 13 October 2012 (UTC)

Could you figure out whether this was copied to Commons or not? The source is claimed to be de:Datei:Kirkjubaejarklaustur.jpg, but that file has been deleted.

old/new Likay article
Hallo Leyo, ich habe als Semesterprojekt meiner Thailaendischen Universitaet einen Wikipediaartikel ueber Likay (in Englisch) verfassen muessen und bin jetzt damit fertig. Irgendwie hab ich davor nicht gesehen, dass es bereits einen solchen Artikel gab und dieser geloescht wurde. Deshalb wollte ich mich erkundigen, weshalb der Artikel geloescht wurde?

Kopexil article
Leyo, regarding the Kopexil deletion nomination reversal: I have tried extensively, but been unable to find a reliable resource (ie. not associated with Kumar organics) that indicates kopexil and aminexil are the same medication. Could you please advise when you have a brief moment? Ramwithaxe talk  22:05, 21 December 2012 (UTC)
 * There is no reason for deleting the article, even if there is no proof of therapeutic effect. It is an actual chemical that has been used (see refs in article). BTW: There is some information on the wordmark Aminexil. --Leyo 00:19, 22 December 2012 (UTC)

Zurich article
I am curious why you reverted my edit removing the reference to Züri as Swiss German for Zurich? Your edit simply said Correct Term in Swiss German. I've made arguments otherwise, including the obvious ones in the edit description when I removed it. You did not address the argument. Reversion is not helpful, and lacks a proper reference. It is hard not take offense to this since zero effort was made to address the issues brought forward for why it is inappropriate to put Züri at the top as a Swiss German name in the global sense. The standard is that a proper reference is required for information included in Wikipedia. This is an English Wiki. Referencing another, flawed, Wiki article in another language hardly qualifies. If you are familiar with dialect, then you would know that pronunciations can differ greatly between different regions. How then would one propose to assert a global Swiss German pronunciation? Or spelling? I know for a fact that Züri is not used in other areas, Graubunden being one. I also know that Zürich would be used in dialect if for instance you were referening a section of the city, such as Zürich-Schwamendingen would typically become Zürich-Schwämmi. There is no reason it couldn't be Züri-Schwämmi. In fact, it would have to be if Zuri was the proper Swiss German. I really don't understand why it is so offensive to deal with this issue in the proper context in the text, making it plain that it is Züri dialect in addition? Please address the issue. If I'm wrong, if Zürich is hochtdeutsch, and you have a reference for that, I'd be very grateful to have the information. If I see no appropriate response to these issues in the near future, I will again delete the reference to Züri at the top of the article and expect not to have to deal with continual reversions for no justifiable reason. — Preceding unsigned comment added by 84.73.150.55 (talk) 21:00, 15 January 2013 (UTC)
 * Don't be silly. A reference (in the lead) for such an obvious fact is superfluous. Don't you know Züritipp, Züri schlaflos, Züri Fäscht, TeleZüri or Züri-Slangikon? --Leyo 21:52, 15 January 2013 (UTC)
 * And you are the arbiter of right and wrong? How reasonable of you. I've given examples of WHY I think you are wrong.  You refuse to address them DIRECTLY, and then add spurious NOISE with examples that are specious, given that at NO POINT have I denied the rampant use of the term Zuri.  I've even referenced the importance of addressing the term PROPERLY and in slightly more depth than currently.  That you can find examples of the term being used in no way contradicts the arguments put forward above.  So perhaps YOU should stop being silly before this degenerates from a discussion to something else.  I am reverting to my original edit.  If  you or anyone else changes it back without a justification that amounts to more than an argument of just-because, that will be 3.  At which point my edit stands until a consensus is agreed.  I had a reasoned argument for making my original edit.  I've seen no counter-argument from anyone yet.  That is not how this is supposed to go.  Which begs the question of why you interjected yourself into the original discussion since you've added nothing new or constructive.  Perhaps recruited to the cause?  — Preceding unsigned comment added by 130.60.228.142 (talk) 12:35, 16 January 2013 (UTC)

ScienceDirect revert
I noticed you reverted my edit which redirected ScienceDirect to Elsevier. Allow me to explain my rationale in making this edit: ScienceDirect is clearly not notable independently of being a means by which Elsevier posts articles from its journals online, and coverage of it in independent reliable sources is very scant. There are no such sources in the current version of the article, for example. Therefore I think a redirect is appropriate since notability is not inherited. Jinkinson  talk to me  23:07, 14 March 2014 (UTC)
 * I noticed your redirected the article despite of opposite conclusions on the talk page and especially [//en.wikipedia.org/w/index.php?title=ScienceDirect&diff=599637945&oldid=594684967 without providing an explanation]. I strongly refuse to accept such a behavior. As I disagree with your conclusion I improved the article, partly with your text. --Leyo 23:33, 14 March 2014 (UTC)

Image
Hi! I saw this image is used on this article. IMHO, the image should not be used as the stick holder is not Japanese, a factual error. It should be used with this type of stick, probably Indian incense. It is dangerous to use the stick holder with Japanese incense because it could catch fire. I think the holder should be cropped at here. See Japanese incense, and Incense of India. Regards. Oda Mari (talk) 16:43, 9 April 2014 (UTC)
 * Hi the image description does not state "japanese incencse holder". And the incense holder will not catch fire more or less from japanese incense without wood stick inside or from indian with wood inside (by the way I am a work safety professional with at least some experiance in such things). This is simply not the case, because in the (hard wood) holder the stick ist extinguished as soon it reaches the holder. I tried ist some 1000 times too ;-). But be free to crop the holder, no problem for me....Better images are welcome too. -Andy king50 (talk) 19:35, 9 April 2014 (UTC)

Page reverted
Hello,

I have searched in vain for the good path to get administrator’s help for the following issue and so I decided to send this request to some including you. I have considerably expanded the article Guerrilla filmmaking and took care in referencing it as far as I could (over 90 links to trustful sources). I am an experienced editor of Wikipedia. For my surprise, the article was reverted by user CIRT to a preceding stub version mainly consisting of a very narrow list of films. Many important contents were removed. Self promotional vandalism seems to be the reason of such intervention, sustained by acute threats. I do not intend to respond with helpless and inconsequent arguments and the time I have to dedicate to Wikipedia is quite limited. I’d be happy if you could pay some attention to this occurrence and let you decide whatever you think is reasonable.

My best,

Tertulius (User talk:Tertulius) 06,44, 15 November 2014 (UTC)

Image help
Could you use your admin powers to find out what has happened with an image on German Wikipedia?

File:Bergen-auf-ruegen-rugard-turm-blick-nordost-bodden-ostsee thfr.jpg claims to come from de:Bild:Bergen-auf-ruegen-rugard-turm-blick-nordost-bodden-ostsee thfr.jpg. The file on German Wikipedia has been deleted with the log message "Eine identische Datei ist unter gleichem Namen auf Commons verfügbar. Sämtliche Metainformationen wurden korrekt übertragen." The file with the same name on Commons is not the same as the file on English Wikipedia.

Was the file on English Wikipedia ever uploaded to German Wikipedia under this name? Is the text in the log message on German Wikipedia incorrect? If the file can't be found on German Wikipedia, then I guess that the file on English Wikipedia doesn't have a valid source. --Stefan2 (talk) 14:56, 17 November 2014 (UTC)

Structure files
Your rv's are fine with me. I got their names from listing in Category:Chemical pages with an eponymous image available, I concluded by their name only. Do you think we can remove that category altogether? Or does it still have a function? -DePiep (talk) 23:26, 18 December 2014 (UTC)
 * The category is fine, but before adding an image found on Commons, some basic investigations are needed. At least the article itself, its talk page and history need to be checked. What about placing a warning onto the category page? BTW: I nominated these inappropriate structures for deletion. --Leyo 23:46, 18 December 2014 (UTC)
 * Go ahead, you know what the warning should sound like. It's not my home territory, so I'll leave it alone. btw, another option is to add a comment in the article (chembox): &lt;!-- file xyz.svg is not correct here -->. Or, I can add a parameter xyz.svg to {chembox}, to with encoded effect that that page will not appear in the category anymore. Just some ideas. -DePiep (talk) 23:52, 18 December 2014 (UTC)
 * I added a warning. You may want to improve the wording.
 * For cases where the file on Commons cannot be moved (did it in one case) or deleted (two potential cases), it may be a good idea to add a hidden comment to the chembox. --Leyo 01:26, 19 December 2014 (UTC)

File:Gigi altro.jpg
Can you help with this file? It says that the source is de:Datei:Gigi altro.jpg, and [//de.wikipedia.org/w/index.php?title=Spezial:Logbuch&page=Datei%3AGigi_altro.jpg Special:Log] reveals that German Wikipedia has had two files with that name. The most recent one (by de:User:Jenson P) seems to be the one on Commons under the same name, and the one on English Wikipedia is presumably the one uploaded by de:User:Aquazurra. That one was deleted in 2008 for the reason 'Seit mindestens 14 Tagen ohne korrekte Lizenzierung'. The upload log summary says 'Quelle: privat' which I presume means 'own work' (although it also could mean that the user just owns a copy of a photograph taken by someone else) and the upload log also mentions de:Template:Bild-GFDL, meaning that the file had a copyright tag.

Was the 2008 deletion on German Wikipedia correct? If so, then the file should probably be nominated for deletion on English Wikipedia too. --Stefan2 (talk) 18:15, 29 March 2015 (UTC)

FC Zurich
Hi Leyo, Per WP:BURDEN, I have challenged unsourced statistics that have then been added back without any attempt to provide a source, despite me requesting on the users talk page. Regarding the notable players listing, there is a clear Manual of Style developed through longstanding consensus for this sort of thing. At every stage I have highlighted this in my edit summary. Elements that the other editor has made that have aligned the list with the required consensus have been left, elements that continue to fall well short of this requirement have been removed. At each instance the editor has been clearly directed to the area of the manual of style which continues to be contravened.

I am really not sure what discussion on the talk page would achieve (especially given that the user does not attempt to communicate in edit summaries and has not bothered to respond to my (admittedly belated) attempts to communicate directly on his talk page). Policy is clear, challenged information should not be added back without a reliable source and long standing consensus is clear at WP:FOOTY concerning how lists of notable players should be treated in club articles. A discussion between two editors on an article talk page would be an inappropriate forum to attempt to alter either policy or wider consensus. Fenix down (talk) 11:22, 15 March 2016 (UTC)
 * Two longstanding users with opposite opinions (each of them thinks he's right), multiple reverts → edit war.
 * One's point cannot be forced through an edit war. You should have asked for an uninvolved party to step in. --Leyo 22:12, 15 March 2016 (UTC)

Hi Leyo, I've put the correct source-references for the Player Records section on the Talk:FC Zürich page with explanation on the source and the 'edit war' (which was not my intention to end in!). Since I'm blocked to edit the the site at the moment I'm unable to add them but will sure do if those sources and the new section are accepted. Fischbach (talk) 09:58, 19 March 2016 (UTC)

MIREX (music)
Dear Leyo,

Since I have just started contributing to Wikipedia, I am still not familiar about the processes. Sorry for this. You marked the article "Music Information Retrieval Evaluation eXchange" as "considered for deletion". I have just started with cleaning up certain Wikipedia pages that are connected to the research area "Music Information Retrieval" (MIR). MIREX is an important component of that research area. Therefore, I think it should be included in Wikipedia. Since I have to synchronize/discuss many things with colleagues, it will take a couple of days until everything is in a good shape. The main changes concerns the following sites:

https://en.wikipedia.org/wiki/International_Society_for_Music_Information_Retrieval https://en.wikipedia.org/wiki/Music_information_retrieval https://en.wikipedia.org/wiki/Music_Information_Retrieval_Evaluation_eXchange

Please reconsider your recommendation after these changes have been made. Of course, I am grateful for any helpful comments.Meinard.mueller (talk) 14:54, 31 March 2016 (UTC)

Blaise Nkufo / Tiny Ruys
There was no "AWB error" on Nkufo and no "rollback vabdalism" on Ruys - it was the removal of unsourced material about BLPs. GiantSnowman 08:38, 30 May 2016 (UTC)
 * It seems to me that you need to learn how to use the edit summary properly. “clean up using AWB” does clearly not correspond to this massive removal of valid content.
 * Rollbacking is to fight vandalism. Any other reverts need to be (very briefly) reasoned. As you have previously been made aware, 60% of editors whose edits had been reverted without any explanation said that this made them less likely to edit, while only 9% of editors whose edits had been reverted with explanation felt less inclined to edit. Hence, consider this inappropriate warning as being directed to yourself. --Leyo 10:18, 30 May 2016 (UTC)
 * It seems to me that you need to read WP:NOTVAND. "Clean up" does refer to the removal of unsourced content about living people. The warning aimed at the IP was appropriate (though I fully acknowledge that I should have selected 'unsourced' rather than 'vandalism' option). GiantSnowman 12:38, 30 May 2016 (UTC)
 * “clean up using AWB” refers to technical clean-up, not to removal of content. --Leyo 21:44, 30 May 2016 (UTC)

Please use my talk page
if you want to say something to me, please do it on my talk page, not Materialscientist's. --Floquenbeam (talk) 23:26, 7 November 2016 (UTC)
 * It fits to the issue raised there. --Leyo 23:34, 7 November 2016 (UTC)
 * Well, I disagree with you in this case, but I'm not going to clog up Materialscientist's talk page with it. I guess we can do it here. Mass rollback was (according to the bot owner who requested his edits be rolled back) the only practical way to undo the +/- 1500 edits. He plans to re-run the bot later to add back the reverted edits that were correct. I'd hoped that mass rollback allowed a custom edit summary, but it didn't. Apparently Writ Keeper has written a version that does allow a custom edit summary, which I'm going to install and play with shortly. I suggest waiting for Headbomb to re-run the AWB run with the correct parameters, but if you want to revert any more of the edits I made before then, feel free. --Floquenbeam (talk) 23:39, 7 November 2016 (UTC)

Two-Factor Authentication now available for admins
Hello,

Please note that TOTP based two-factor authentication is now available for all administrators. In light of the recent compromised accounts, you are encouraged to add this additional layer of security to your account. It may be enabled on your preferences page in the "User profile" tab under the "Basic information" section. For basic instructions on how to enable two-factor authentication, please see the developing help page for additional information. Important: Be sure to record the two-factor authentication key and the single use keys. If you lose your two factor authentication and do not have the keys, it's possible that your account will not be recoverable. Furthermore, you are encouraged to utilize a unique password and two-factor authentication for the email account associated with your Wikimedia account. This measure will assist in safeguarding your account from malicious password resets. Comments, questions, and concerns may be directed to the thread on the administrators' noticeboard.

A new user right for New Page Patrollers
Hi.

A new user group, New Page Reviewer, has been created in a move to greatly improve the standard of new page patrolling. The user right can be granted by any admin at PERM. It is highly recommended that admins look beyond the simple numerical threshold and satisfy themselves that the candidates have the required skills of communication and an advanced knowledge of notability and deletion. Admins are automatically included in this user right.

It is anticipated that this user right will significantly reduce the work load of admins who patrol the performance of the patrollers. However,due to the complexity of the rollout, some rights may have been accorded that may later need to be withdrawn, so some help will still be needed to some extent when discovering wrongly applied deletion tags or inappropriate pages that escape the attention of less experienced reviewers, and above all, hasty and bitey tagging for maintenance. User warnings are available here but very often a friendly custom message works best.

If you have any questions about this user right, don't hesitate to join us at WT:NPR. (Sent to all admins) .MediaWiki message delivery (talk) 13:47, 15 November 2016 (UTC)

Question
Hello Leyo,

I am currently facing some sort of an unfortunate problem. I have asked both Alex Shih and Bbb23 about this; I suppose I have annoyed both of them and I have no idea whom I am supposed to ask at this point. As you know, I have been tbanned from automobile and units of measurement (not complaining how unfair that was at this point); and, well, I have been found guilty of evading the topic ban because I had both asked another editor to refrain from adding original research to an automobile article and editing an article that was later declared automobile-related (ignoring my arguments and literature on the topic but not citing any sources). As the result, I have been blocked for 6 months for topic ban evasion. I definitely do not want to get blocked again for the same reason (that would most likely be an indefinite block), but I have no idea how to contribute to Wikipedia without accidently violating the tban. 'Automobile' and 'units of measurement' is just not very precise (technically I am violating the topic ban by signing my posts on talk pages as it adds units of measurement to it (date and time)); some have said that I am taking the ban too broadly, but then some topics were declared 'ban related' when I thought they were not. It was also suggested that the ban gets suspended (so I could prove that I am a proper editor), but other administrators have said that I can prove it without a ban suspension by creating some nice articles and the ban was not suspended. Now I have no idea what to do. I am obviously a knowledgable editor (just some good and featured article examples 1, 2, 3, 4) but the line between the non-automobile articles and the automobile articles is not very precise in this case. I have tried to write some non-automobile articles but I fear that some 'expert' would declare them automobile/unit of measurement-related even though they are not in my opinion. Could you do me a favour and read these articles I have already written and tell me what you think about them? It requires about 7 minutes of your time. Best regards, --Johannes Maximilian (talk) 00:21, 11 August 2018 (UTC)
 * Could you please ask someone else/somewhere else? I am currently short in time due to real life. It would take me much more time than 7 minutes to give you an informed reply. Additionally, I was involved in your case previously. Therefore, it would be best to ask for another view without prejudice. --Leyo 21:58, 12 August 2018 (UTC)


 * Well then, thank you. --Johannes Maximilian (talk) 14:38, 13 August 2018 (UTC)

Isothiazolinone
Thanks for your help on isothiazolinone. The article in the Biological implications section says isothiazolinone, not derivatives. So I think this is confusing. How can they both be right? — Preceding unsigned comment added by Kelly222 (talk • contribs)
 * The sentence you seem to refer to says “Isothiazolinones are antimicrobials used to control bacteria, fungi, and algae in cooling water systems, fuel storage tanks, pulp and paper mill water systems, oil extraction systems, wood preservation and antifouling agents.”, i.e. isothiazolinone s (= derivatives of isothiazolinone), not isothiazolinone as such. --Leyo 20:29, 23 October 2018 (UTC)

Oh. I see. Thanks. I didn't know that an s on the end changed the meaning that way. Perhaps the article can show that. Kelly222 (talk) 00:21, 25 October 2018 (UTC)
 * Well, “Isothiazolinones” may get replaced by “Derivatives of isothiazolinones” or so. --Leyo 21:49, 26 October 2018 (UTC)

Administrator account security (Correction to Arbcom 2019 special circular)
ArbCom would like to apologise and correct our previous mass message in light of the response from the community.

Since November 2018, six administrator accounts have been compromised and temporarily desysopped. In an effort to help improve account security, our intention was to remind administrators of existing policies on account security — that they are required to "have strong passwords and follow appropriate personal security practices." We have updated our procedures to ensure that we enforce these policies more strictly in the future. The policies themselves have not changed. In particular, two-factor authentication remains an optional means of adding extra security to your account. The choice not to enable 2FA will not be considered when deciding to restore sysop privileges to administrator accounts that were compromised.

We are sorry for the wording of our previous message, which did not accurately convey this, and deeply regret the tone in which it was delivered.

For the Arbitration Committee, -Cameron11598 21:03, 4 May 2019 (UTC)

Google Code-In 2019 is coming - please mentor some documentation tasks!
Hello,

Google Code-In, Google-organized contest in which the Wikimedia Foundation participates, starts in a few weeks. This contest is about taking high school students into the world of opensource. I'm sending you this message because you recently edited a documentation page at the English Wikipedia.

I would like to ask you to take part in Google Code-In as a mentor. That would mean to prepare at least one task (it can be documentation related, or something else - the other categories are Code, Design, Quality Assurance and Outreach) for the participants, and help the student to complete it. Please sign up at the contest page and send us your Google account address to google-code-in-admins@lists.wikimedia.org, so we can invite you in!

From my own experience, Google Code-In can be fun, you can make several new friends, attract new people to your wiki and make them part of your community.

If you have any questions, please let us know at google-code-in-admins@lists.wikimedia.org.

Thank you!

Category:Chemistry images
Hi! Today i found an old deletion request I made years ago for more than 1000 files in Category:Unclassified Chemical Structures. Since you were the latest to comment on Category_talk:Unclassified_Chemical_Structures I thought I would ask you if you know if anyone is looking at these chem images. --MGA73 (talk) 20:07, 18 October 2020 (UTC)
 * The two images directly in that category should be moved to Commons, whereas the remaining nine images in the subcategory Classified Chemical Structures (all in use) are of poor quality and need to be converted to SVG. --Leyo 08:59, 19 October 2020 (UTC)
 * File:Periodic Table by Quality.PNG is tagged not-for-commons; but it's not a chemical diagram, so it doesn't belong in this set of cats at all. File:Circular interdigitated electrodes with and without gold nanoparticle chemiresistor film.jpg I agree should go to commons. That would clear out the main Category:Chemistry images. I cleared out Category:Unclassified Chemical Structures‎ earlier today. DMacks (talk) 09:18, 19 October 2020 (UTC)
 * I moved the latter to Commons. Concerning the former, I don't agree with its tag. --Leyo 10:25, 20 October 2020 (UTC)
 * Sorry for the late reply. Its so great that you moved some files allready and nominated other for deletion :-D I think files should be moved to Commons even if they are in English.

Administrators will no longer be autopatrolled
A recently closed Request for Comment (RFC) reached consensus to remove Autopatrolled from the administrator user group. You may, similarly as with Edit Filter Manager, choose to self-assign this permission to yourself. This will be implemented the week of December 13th, but if you wish to self-assign you may do so now. To find out when the change has gone live or if you have any questions please visit the Administrator's Noticeboard. 20:06, 7 December 2021 (UTC)

Edit conflict: Nonenes
Looks like I've had an edit conflict with you at nonenes and I've overwritten your edit as a result. Apologies for that. It looks like you were fixing the table I coped over from de:wiki. I think I've made most of the same fixes in my edit. --Project Osprey (talk) 13:45, 10 May 2021 (UTC)
 * No problem. Should be okay now. BTW: I will review your proposal concerning pyridine ASAP. --Leyo 16:08, 10 May 2021 (UTC)

How we will see unregistered users
Hi!

You get this message because you are an admin on a Wikimedia wiki.

When someone edits a Wikimedia wiki without being logged in today, we show their IP address. As you may already know, we will not be able to do this in the future. This is a decision by the Wikimedia Foundation Legal department, because norms and regulations for privacy online have changed.

Instead of the IP we will show a masked identity. You as an admin will still be able to access the IP. There will also be a new user right for those who need to see the full IPs of unregistered users to fight vandalism, harassment and spam without being admins. Patrollers will also see part of the IP even without this user right. We are also working on better tools to help.

If you have not seen it before, you can read more on Meta. If you want to make sure you don’t miss technical changes on the Wikimedia wikis, you can subscribe to the weekly technical newsletter.

We have two suggested ways this identity could work. We would appreciate your feedback on which way you think would work best for you and your wiki, now and in the future. You can let us know on the talk page. You can write in your language. The suggestions were posted in October and we will decide after 17 January.

Thank you. /Johan (WMF)

Hi. Your editsummary is misleading, and you have downgraded template code without discussion. Please revert and stop editwarring. -DePiep (talk) 14:13, 12 January 2022 (UTC)
 * It is not. Please stop. --Leyo 15:27, 12 January 2022 (UTC)

Copyright problem on Perfluorooctanesulfonic acid

 * How come that you believe that text of a UN Convention isn't in the public domain as other legal text is? See also e.g. c:Template:PD-UN-doc or c:Category:United Nations Treaty Series. --Leyo 21:39, 14 February 2022 (UTC)
 * Sorry my computer won't let me open this verson; the one where I found the matching content is here. The page is marked at the bottom as "Copyright 2019 by Stockholm Convention" and the Terms of Use says "All contents of the Stockholm Convention Web Site are: Copyright 2019 by Stockholm Convention and/or its suppliers. All rights reserved." So the page is definitely not "published by the United Nations without a copyright notice", and was no "left in the public domain" — Diannaa (talk) 22:13, 14 February 2022 (UTC)
 * The decision I linked (just ignore the warning or use another browser) is the original source of the text. The claim ("Copyright 2019 by Stockholm Convention") appears on all pages of that website. However, on the page you linked is clearly inappropriate for the reason stated. --Leyo 22:17, 14 February 2022 (UTC)
 * I have tried on two different computers. Mine is a Chromebook, which uses Chrome exclusively. It won't let me even attempt to load the page. I got a warning while using Firefox on a different computer, but it's not my computer so I can't ignore the "security risk" warning. The United Nations website also has a copyright notice, and their Terms of Use specifies that commercial use and derivative works of their material are not allowed. Sorry but I am not going to be able ignore the valid copyright notice on the document where I found the matching content, or the information at the UN website.— Diannaa (talk) 22:34, 14 February 2022 (UTC)
 * You don't need to do anything else in this matter. --Leyo 23:02, 14 February 2022 (UTC)
 * If I may chime in (I'm active at German Wikipedia's copyright village pump, de:WP:URF, where this case was also discussed): I would interpret the copyright notice on the website of the Stockholm Convention as a blanket notice of the kind that is often applied to the footer of a web page, which doesn't mean that all documents found on the website are necessarily protected by copyright. The same applies to the general terms of use. Often, such websites also contain PD documents or use photographs that are out of copyright, which will not be changed by blanket copyright notices. In this case, I agree with Leyo that legal texts of UN conventions are in the public domain. More broadly speaking, laws, international conventions etc. are usually PD, as everyone needs to be able to access and use them, and such a provision is in the copyright law of most countries. Gestumblindi (talk) 11:03, 15 February 2022 (UTC) PS: If your computer won't let you open the PDF, maybe you're using a newer version of Firefox? For some reason, Firefox considers all PDF files that aren't downloaded via HTTPS a security risk now, but you can choose to download it anyway. Personally, I don't think that downloading a PDF via http is a huge risk. Gestumblindi (talk) 11:05, 15 February 2022 (UTC)
 * Leyo, if you want to get a second opinion, I suggest asking one of the people on this list, or posting at WT:CP.— Diannaa (talk) 16:02, 15 February 2022 (UTC)
 * Thank you for this suggestion, but the case is clear. --Leyo 16:20, 15 February 2022 (UTC)

New administrator activity requirement

PFAS Revert
You reverted all PFAS to PFASs, even though the discussion had ended and you had no longer defended your position.

But you also reverted all my copy edits as well. You should have gone back and manually made the changes from PFAS to PFASs, and not done a complete reversion.

I'm also of the opinion that your defense of the use of PFASs instead of PFASs is wrong - the much more common usage is PFAS, and it makes no sense to pluralize an already plural word. By the definition we are using on the wiki page itself, the S stands for substances, and it makes no sense to say "substancess".

Please undo your reversion and keep my copy edits in place. Thank you. — Preceding unsigned comment added by 71.11.5.2 (talk • contribs)
 * You blindly changed the acronym just everywhere, including in file names (the images were not shown anymore), in titles of publications, in quotes. This is considered vandalism!
 * I only didn't continue the discussion because you keep repeating yourself. Also your argument above is not valid. With the same argument, you could also claim that the acronyms of polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) or polycyclic aromatic hydrocarbons (PAHs) should not have an s at the end. --Leyo 08:11, 24 June 2022 (UTC)
