How to make specified forums visible on index page but not allow to view their threads? Users should know that specified forum exists but they can't view/read it's threads.
There's a usergroup permission called "Can view threads" or something similar, just uncheck that box and check the "Can view forum" box for the usergroups you want.
ooops that was so easy, now I feel myself stupid
sorry for that obvious thing
No problem, found it myself recently, glad I could help.
