AdminWelcome, 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 Commons:Deletion requests), 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.
Please feel free to join us on IRC: #wikimedia-commons on irc.freenode.net. There is also a channel for Commons admins, which may be useful for more sensitive topics, or coordination among administrators:#wikimedia-commons-admin.
You may find Commons:Guide to adminship to be useful reading.
