Well, there were lots of steps. Mostly it was changes to the CSS so the first step would be to take a look at my CSS. I didn’t change any non-theme related files. The plugins I’m using are BBcode buttons toolbar, BBcode lite, bb topics view, and post Count plus. Probably the main thing I do different is that regular users shouldn’t see the admin pages of BBpress. Instead they get redirected to the wordpress admin pages.
Sambauers put a great video together on how to get wordpress and bbpress working together:
