Colors
Hi. Could you please delete the page User:A2569875/Fast Page/Color or at the very least remove the tranclusion of the color templates? The templates are categorized without a noinclude exception so your user page shows up in all the corresponding categories. This should be avoided and in fact I discovered your page through Database_reports/Polluted_categories. Thanks, Pichpich (talk) 02:41, 4 April 2011 (UTC)
 * I went along and commented out the templates. Let me know if you have a problem with this. Pichpich (talk) 22:31, 5 April 2011 (UTC)

interwiki links
I noticed you adding links to the Chinese WP on pages on my watchlist. You do not need to do that to English WP pages any more: interwiki links are now hosted on Wikidata. To add a link use the 'Edit links' button on the page under the links. I've done it for the three pages you added links to, the links on the pages will probably be removed by a bot. Eventually all interwiki links will be on Wikidata, but the English WP is the first I think.-- JohnBlackburne wordsdeeds 23:51, 2 March 2013 (UTC)

Hyperoperation with reals
Hi! I saw your wiki page about the Hyperoperators. And I am really interested in that how could you calculate H1.5(3;3) and H2.5(3;3). Please, tell my the methods. Thank you very much. — Preceding unsigned comment added by Xorter (talk • contribs) 07:12, 3 May 2016 (UTC)

File:PsH.png
Hi Yu-Fan.

Thanks for making up molecule images. I noticed your image at commons:File:PsH.png and used it in the article on Positronium hydride. However the positronium is actually bigger than hydrogen. Positronium is 3.48 au, hydrogen 2.8 au, and the separation 3.66 au. I suppose ball and stick model does not have to be too representative. But do you have the software to redraw this with positronium bigger? Graeme Bartlett (talk) 23:13, 27 September 2016 (UTC)

gallery
Hi. You have made many great images. Can you add link to your uploads or gallery ? TIA --Adam majewski (talk) 18:41, 6 April 2018 (UTC)
