You can enter into your console:
ClientCmdSetAdminLevel(%arg);
Where %arg is:
0 for no Admin
1 for normal Admin
2 for Super Admin
(and if you put anything higher, it will show up as the number)
Note that this only is visible to you, and not to the rest of the server.
The only time this command is useful is if the server has you registred as an admin, but your client doesn't.
Entering this will allow you to open the admin menu, but no actual information will show up. (No, you can't use any of the buttons, either, unless the server says you're an admin.)
