Manual:User rights

User rights are specific access and ability permissions that can be assigned to customizable groups, which can then be assigned to (or removed from) users through the Special:Userrights interface. For example, the default bureaucrat group enables the use of the User rights interface.

This feature was introduced in MediaWiki 1.5; see setting user rights in MediaWiki on the Meta-wiki for earlier methods.
