I upgraded to wp 2.5 and I found that my previous bbpress integration didn't work anymore.
I checked bbpress.org and developers had a fresh new version waiting there but it is such a pain upgrading and re-touching the whole integration that I gave up bbpress forum.
You know this is going to happen sooner or later; bbpress as a wordpress plugin or fully integrated in the wordpress package. Starting forums on wp single posts, on wp static pages, no more need of integrating headers or calling all wp functions twice, integrating forms, templates, single click installation...
