Denying access to forums

[Miguel86]

Hi:
I have one problem. All my users when are registered are in the same group. However i have a Special group where i change user to (not an additional group, the primary of the user) called Warned and this group should have access to fewer forums than normal users. But i'm unable to restrict it, because when i created the group i selected that this group can see only 2 forums, but if you enter with an user account that has that group as primary you can see the same forums :S Any help please?

every member belongs to the post-count groups...   so, regardless of their primary or secondary groups... if the post-count groups have access, so will everyone.

Ok, thanks.
