MemberGate uses a roles based security system that allows you to define the role or authority of those that visit or contribute to your site.
This means you can have members, content providers, department managers, assistant site managers, site managers, and more - each with clear restrictions on what they can and can't do on your site. The roles based system is designed so that when members sign in, they can only see and access the material and options that are within their scope of authority.
