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.
Administrators assume these responsibilities as volunteers who go through a community review process. They are not acting as employees of the Wikimedia Foundation. 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. Administrators should not be confused with Wikimedia system administrators ("sysadmins").
The English Wikipedia has 1,334 administrators (see full list of accounts with administrator privileges or lists of administrators by activity level).
