Page/Forum integration

Hello,

I have been working on integrating my phpBB forum into my Wordpress Blog.

I nearly have it all figured out but I am stuck on one part, it's probably simple.

If you visit my site, http://www.Tip20.com and click on "Forum" at the top you will see that it opens the forum up without the right sidebars as I intended. No problem.

But if you click on any link in the forum, you will see that it opens into the center column and the right sidebars are back. I don't know how to determine what "page(s)" to tell Atahualpa to not display the sidebars on in this case. Any ideas?

( If I must, I can make my minimum width larger and just keep the right column, but I'd rather not as the site is almost to wide already)

Thanks for any help here!
Tom
