According to a lot of cms sites, the site administrator has full access to every aspect of the site,,, well, in Dolphin, the administrator is limited to the standard membership access set in the system membership actions.
Ideally, not only should there be a non-members, standard and promotion, but there should be a specific level for administrators, that regular uses can not have access to, and seeing that there isn't one, the site administrator is bound by the system actions of a registered user.
To create a membership of that level, would mean it gets shown in a users membership and is able to purchase that level and gain full access (definitely not acceptable).
In A/V chat I set up a private room for site moderations and admins, and set it so that standard access is not permissible, but doing that, also prevents an admin from entering the room, because of the 'Standard' access the admin has.
