Usergroup/Forum Permissions Question
 

I have a "Registered" usergrorup that has access to my classifieds section. Someone in the "Registered" (has full access to the forum) primary usergroup can also have an additional usergroup called "Premium" (also has full access to the forum). I also have a user group called "No Classifieds" wich I want to use to prevent members from having access to the classifieds. The forum permission for the "No Classifieds" user group in the classifieds forum is set to "no" for "Can View Forum".

Can I simply ad the "No Classifieds" usergroup as an additional usergroup to a member to prevent them from having access to the classifieds while still having the benefits of the "Premium" additional usergroup ?
