You may be interested in Requests_for_arbitration/Kehrli given your comments on the mass spectrometry related talk pages.--Nick Y. 17:27, 28 August 2006 (UTC)
 * Thanks for the positive feedback on mass-to-charge ratio etc. I am still a little concerned about the common usage of this term and the prefered units in the electron optics and related (i.e. non-mass spec) fields. In my limited experience in pure electrodynamics (non-MS) I remember solving problems involving m/q but do not remember using Da/e. I think this needs to be validated. I can't find it in the literature with a quick search but then it is a hard search term. Additionally, although I know that m/q enters into teh physics of many of teh fields listed (other than mass spectrometry) I have yet to see evidence that there is use of the term "mass-to-charge ratio" in these fields or that it is somehow notable. In fields that involve electron optics I see no advantage to using Daltons, and no point in stopping at the m/q relationship since the mass and the charge are known. Why not just solve the problem and be done. Accelerator physics and ion optics I get stopping at m/q. I still would think that for the most part SI units would be more handy.--Nick Y. 17:26, 2 October 2006 (UTC)

Orphaned non-free media (Image:Gilmoregirls s6.jpg)
Thanks for uploading Image:Gilmoregirls s6.jpg. The media description page currently specifies that it is non-free and may only be used on Wikipedia under a claim of fair use. However, it is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the media was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that media for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that all non-free media not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you. BetacommandBot 13:38, 9 September 2007 (UTC)

ArbCom 2023 Elections voter message
 Hello! Voting in the 2023 Arbitration Committee elections is now open until 23:59 (UTC) on. All eligible users are allowed to vote. Users with alternate accounts may only vote once.

The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to impose binding solutions to disputes between editors, primarily for serious conduct disputes the community has been unable to resolve. This includes the authority to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail.

If you wish to participate in the 2023 election, please review the candidates and submit your choices on the voting page. If you no longer wish to receive these messages, you may add to your user talk page. MediaWiki message delivery (talk) 00:28, 28 November 2023 (UTC)
