An administrator has stronger privileges then a normal contributor but not as strong as a Bureaucrat which they have the ability to promote new admins and demote admins who have severely abused their privileges.

An Administrator can control how security is exerted on their contributors along with blocking those who defy their authority in enforcing the policies.

The administrator can grant certain rights like rollback so contributors can undo edits or promote them to chat moderator to manage busy chat sessions.
