The answer to my question may already be here, and I just haven't looked hard enough, however, what was the working way to allow guests and members to see forums that are restricted to them, and not access them?
And to the person that didn't understand why anyone would want to be able to do this, it's simple.
You have the forum "100 Post Club" that only allows a member group that has atleast 100 posts to access it, and you're using this as motivation to keep your members active. Well, this does no good if people with less then 100 posts can't see the forum.
