Well, i dont know if i am missing something, and if i am, tell me, but the only way i find i can get to forums to browse is to just thing of something to search for and link to it from there. why not just put a link on the main page to the forums.
There is also a 'Discussion Forums' link at the top right of the main page (below 'Fight-Back!' and above 'Security Downloads')
From there you can browse the forums or choose from the following options:
AntiOnline FAQ | View Unanswered Posts | View New Posts | View New Usenet Posts | Search Posts | Mark All Forums Read.

Cheers
