WordPress uses a concept of Roles, designed to give the website owner the ability to control what users can and cannot do within the site.
Due to the large number of third party plugins that use Roles, we've decided not to alter the Roles structure within our themes.
The basic usage for Roles within our themes follow that of the basic WordPress setup.
Administrators - This allows users into the admin area
Subscriber - This allows users to login and access the front end member pages.
No other roles are used within our themes.
