Using UAM and loving it, by far one of the best pugins for advanced user management out there.
Not sure if this is even possible with UAM:
1 . Have a public page where future users fill out the form.
2. Users are added to a group that sees categories assigned to it.
3. I'd like to hide the page with the form for the users in that group, if they are logged in.
Not sure if UAM is even my answer. Any nudge in the right direction is greatly appreciated.
