Re: I just want header/footer
@ bruinfelix, I looked at your site and you did not integrate the header at all.
@ caming, in my experience it’s not an easy thing to do. There is some info floating around here about using an include to get your WP header to show up on bbPress but it’s not pretty.
My advice to you would be to rebuild it in bbPress and then spend some time making it look smooth. At a minimum this will involve you bringing your header over (either through the style sheet or the header.php) and then recreating your nav bar.
You can see that I’ve done it here…
If this helps at all I’d be happy to answer any questions you have.
