I just posted a topic related to this - my Minge group. They aren't supposed to have access to anything. They inherit rights from Users, which have several commands such as teleport, goto, and god.
At first, I took Gower's and Stickly Man!'s advice to use ulx denyaccess to remove the inherited commands, but I got an error saying Minge didn't have access to it. Then, I tried setting it so Minge can't target anyone, and that didn't work. I tried the following:
1. !*
2. !%minge,!%user,!%regular,!%expert,!%respected,!%admin,!%superadmin,!%owner
3. Restricting each individual command with #2
4. !%user
None of these worked, and the Minge class was still able to use god, noclip, teleport, etc.
Where did I <censor> up? What's the best way to do this?
Also, Users can target !%user,^
EDIT: the Minge group also doesn't have the faded checked boxes like it normally would. The boxes are totally unchecked, even though Users have access to it and Minge inherits that access.
