ChemSim, congratulations! You now have administrator rights on Commons. Please take a moment to read the Commons:Administrators page and watchlist related pages (in particular Commons:Administrators' noticeboard and its subpages), before launching yourself into page deletions, page protections, account blockings or modifications of protected pages. The majority of the actions of administrators can be reversed by the other admins, except for history merges which must thus be treated with particular care. Have a look at the list of Gadgets (on the bottom there are the ones specifically for admins – however, for example the UserMessages are very helpful too).

Please feel free to join us on IRC: #wikimedia-commons ^webchat on irc.libera.chat. There is also a channel for Commons admins, which may be useful for more sensitive topics, or coordination among administrators: #wikimedia-commons-admin ^webchat.

You may find Commons:Guide to adminship to be useful reading. You can find the admin backlog overview at COM:AB.

Please also check or add your entry to the List of administrators and the related lists by language and date it references.

File:Structural formula of 2-methyl-1-propanol.svg as duplicate

Is there any advantage of this file over the older File:Isobutanol Strukturformel.svg? DMacks (talk) 03:04, 7 May 2026 (UTC)

@DMacks: You are absolute right, it's nearly a 1:1 duplicate. I have replaced all its uses with the older file. I think this one can get deleted now. ChemSim (Talk) 06:54, 7 May 2026 (UTC)
