Excluding sidebar and expanding page

[Redmanthatcould]

Hi there,

I put a forum plugin on my site, and I'd like for any pages related to the forum to not have the sidebar call, and for the body of any forum pages to cover the entire width of the site.

So this is the forum:

http://www.behindthehype.com/forum/

But I'd also like the sub-pages that the forum generates, to not have the sidebar call and have the body expand to the entire width, like:

http://www.behindthehype.com/forum/sports/
http://www.behindthehype.com/forum/spor ... -panthers/

Etc etc

So essentially, anything "/forum/.../" I'd like not to have the sidebar, and for the body to cover the entire width of the page.

Any suggestions on how to tackle this?

Thanks!
