Yes, those tutorials and downloads are meant to use the WP theme. They just call the WP header. I tried this one:
http://www.adityanaik.com/blog/bbpress-and-wordpress-integration/
It works like it says it does, but unfortunately for my site, it looks terrible and doesn’t integrate at all. Looks like I’ll have to modify the forums’ style sheet, which isn’t that bad. It’s just that it would be nice if when I modified one, it worked for both.
Does it integrate the way this site is integrated? Because this site has a couple minor style problems. For example, the header “Simple, fast, elegant” moves around. It doesn’t stay in place when switching between forums and blog.
