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. An administrator, or sysop (system operator), is a user who has been appointed with extra editing powers for maintenance-based tasks. Another way to think of an administrator is as a janitor, as they help keep the wiki a clean and better place by deleting/restoring pages, protecting pages, blocking users/IP editors, editing MediaWiki pages, and viewing deleted archives. Bureaucrats also have the ability give other users rollback*, administrative, or bureaucratic rights after community consensus (* rollback rights do not require community consensus).
