Geeklog Forums

I'll try to keep this short. I have a new GL site up and running very well and if I browse to my site without being logged in I cannot go into media gallery, links, polls etc.. which is the correct behavior since I only want members getting into stuff but for whatever reason the forum, phpbb bridge link will let them view posts just fine but will prompt for a login if you try to post. This seems fine but is there a way to make the forum not even come up without being logged in or is this a limitation of phpbb bridge?
