Wikipedia is a backlog, in and out – there's always plenty of work to do as an admin. This page documents the venues that often require admin attention.
Your best friend for finding work to do is theadmin dashboard. Note that anything highlighted in red in the "immediate requests" table have priority - either due to its severity or that it is heavily backlogged. Many admins transclude this template{{admin dashboard}} in their userspace, providing it options to show only the venues and backlogs they specialize in.[1] See the template documentation for more information.
The following noticeboards are those that do or might require administrator attention.
The citations indicateuser scripts or gadgets that can assist you in responding to reports at that noticeboard. Usage of these is recommended as you may find yourself doing repetitive tasks, and anything to expedite your work means more work can be done and the project is overall better maintained.
These noticeboards fill up quickly, and usually involve matters that require immediate administrator intervention in the form of blocks, page protection, or deletion.
The following venues (not necessarily referred to as a noticeboard) are for pages or items thatmight require deletion or merging.
Every noticeboard differs in some way. Specific instructions for any given noticeboard may be found at the/Administrator instructions subpage. If such page exists, you will see a link to it at the top-right of the noticeboard page. For instance,Wikipedia:Articles for deletion/Administrator instructions (notice the link to this page at the top-right ofWP:AfD).
Instructions are sometimes also found in theedit notice.
Working at some noticeboards can involve repetitive tasks, for which there are some useful scripts to expedite your work. Above in the list of noticeboards, look for citations that denote scripts that may pertain to that venue.
Twinkle applies to any area where you might need to delete, block or protect. Note especially its usefulness when mass-deleting or mass-protecting pages.
