ArbCom 2019 special circularEdit

The Arbitration Committee may require a new RfA if your account is compromised.

Administrator account security (Correction to Arbcom 2019 special circular)Edit

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)


After solving your GHS question within 2.5 hrs, I expected a small "thank you" signal. Any note after that, for example questions and suggestions and comments, sounds better. I don't know your internet environments, but such a new habit could bring you e-friends that want to cooperate more often and intensely. As is my experience. -DePiep (talk) 21:45, 17 July 2019 (UTC)

Well, I could have done that more explicitly than just as “Looks good”. Somehow, I got overwhelmed by the amount of your questions and suggestions. --Leyo 21:33, 22 July 2019 (UTC)
Fair enough. Have a nice edit. -DePiep (talk) 06:25, 23 July 2019 (UTC)

Happy Adminship Anniversary!Edit

Keith BatesEdit

Hallo Leyo, könntest Du mir Keith Bates im BNR wiederherstellen. Ich würde dort gern mal reinschauen, möglicherweise könnte ich das Material auch verwenden. Danke sehr, Doc Taxon (talk) 16:25, 17 November 2019 (UTC)

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


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, 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

Thank you!

reverted edit on "Soap" and "Sodium laureth sulfate"Edit

Hello, you reverted my edit on Soap and Sodium laureth sulfate bc of not following MOS:CHEM. Can you tell me which rule I violated? Thanks in advance.Naturwiki (talk) 07:01, 16 October 2020 (UTC)

Please see Wikipedia:Manual of Style/Chemistry/Structure drawing#Suggested molecule editor settings or de:Wikipedia:Wie erstelle ich Strukturformeln?/Tutorial Strukturformeln#Maße. --Leyo 16:11, 16 October 2020 (UTC)

Category:Chemistry imagesEdit

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#Converting_to_svg_here_or_on_Commons? 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)
@DMacks and Leyo: 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. It is easier for other Wikis to translate to local language if the file is on Commons. --MGA73 (talk) 19:16, 23 October 2020 (UTC)

fake SVGsEdit

Hi Leyo, some time ago, I think you wrote to tell me that my SVG's are fake SVG's, i.e. not really vector graphics but something inferior with an SVG skin. Can you please check this image to see if I am still producing fakes vs the real thing?


Thank you, --Smokefoot (talk) 21:12, 27 October 2020 (UTC)

Your image looks like a real SVG. Thank you for your efforts.
Please note that methyl groups should be denoted with “CH3”, not “Me”. --Leyo 23:53, 28 October 2020 (UTC)
