Maybe you could try to change the anonymous permissions!
There is something at Admin Configuration Panel that allows the admin to make some user, or some cattegory (of users) win or loose some permissions... and to read messages is one of them, I think so...

If you can see Restricted Forums, you haven't configured the General Group correctly. You need to change it from "Allow All" and highlight the Restricted Forums/Categories to NOT be allowed into.
And to keep the Anonymous users from seeing any Categories/Forums, you would need to set the Categories/Forums as restricted and not allow the General Group access to them.
I would suggest having a "viewable" area for visitors to have at least view access to so you have a place to put instructions on how to sign up, rules, etc. You can also set this Forum to not allow anonymous posts or replies to keep it "clean." [originally posted on jforum.net by GatorBait3]
