The Flash Wiki:Administrators

Different users have access to different functions of the site. While anyone can do most things on the site, including reading and editing, administrators can access a few additional functions.

Administrator abilities
These additional functions include:
 * Deleting and undeleting pages, page histories, and uploaded files.
 * Locking (protecting) a page so it cannot be edited or renamed by users without admin rights or autoconfirmed status.
 * Blocking IP addresses or user names from editing; and very quick "rollback" of undesirable edits.
 * Editing the interface by changing system messages and skins.
