Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
The Wikipedia community decides whether articles meet certain criteria to be selected as Featured articles, representing the best that Wikipedia has to offer. A different featured article is chosen to appear on the Main Page every day. Any user can nominate an article as a Featured article candidate, or comment on any of the existing candidate articles.
Administrators, commonly known as admins or sysops (system operators), are Wikipedia editors who have been granted the technical ability to perform certain special actions on the English Wikipedia, including the ability to block and unblock user accounts and IP addresses from editing, edit fully protected pages, protect and unprotect pages from editing, delete and undelete pages, rename pages without restriction, and use certain other tools.
They are never required to use their tools, and must never use them to gain an advantage in a dispute in which they are involved.
Admins are selected by the Wikipedia community at Wikipedia:Requests for adminship through an often grueling review process. Go there if you would like to nominate someone to be an admin (including yourself).
