Administrators, also known as System Operators (Sysops for short), are users who have proved themselves to be a very reliable editor of the wiki and have worked their way up to become an administrator. They are usually the most reliable members of the community and can be contacted with queries. They have the power to delete pages and block users. The purpose of an administrator is to keep peace on the wiki and to keep vandalism at bay.
Administrators can also edit the pages that make up the wiki, such as the sidebar, site notices, MediaWiki pages, and design pages (e.g. js and css pages).
