I have a primary usergroup called noob. This is the main usergroup when noobs sign up. All noobs are manually upgraded to regular membership usergroup (a secondary usergroup). I do not want them to view inside the main subforum called General Chat but let them only see the node and the description (private) in last post info. How do I make so that noobs and guests can see General Chat on node list but as private (can't view forum) but regular members can see even if their primary usergroup is noob?
