Super Administrator 
A superadministrator is essentially another administrator but with additional permissions. For example only a superadministrator can manage other admins.

Superadministrators must be added to the vBulletin config.php file to enable their superadmin status:
//    ****** SUPER ADMINISTRATORS ******
//    The users specified below will have permission to access the administrator permissions
//    page, which controls the permissions of other administrators
$config['SpecialUsers']['superadministrators'] = '1'
