If I remember correctly, a folder will override a wp page. What I have done is, install bbpress at a location within wp, then create a page in wp with the same name that you gave your bbpress install. When viewing the blog, the page will show up in the pages section, menu bar or wherever you theme puts it. This should create a dynamic link to the forum.

I think this is what you are looking for.

I have done this for static folders and things like bbpress.
