How do I adjust user authorizations?

The user profile has an authorizations page.  To access go to Admin >> User Mgmt >> User Profiles.  Then click on the 'Auth' tab. If you make a user a sysop, they will have access to all features except those checkboxes still showing after making them a sysop. See below for a printscreen of the authorizations page.  Offscreen are additional authorization sections for maintenance and Online Billing.
