I have moved both groups ($levels in txp) and permissions ($txp_permissions) in to the database. There is a very basic UI to allow adding and deleting each, but nothing that allows assigning permissions to a group. I am in need of UI design assistance on how to make this happen in an easy to use way for the user. I can write the php code to sit behind the interface you design.
There is no spoon...only a fork. ;-)
