Re: Forum integration 101 needed!
The only way to do this, is with “deep integration.”
You will want to scour the bbpress.org forums for some more information about how to do this.
I’m going to assist Trent in including deep integration as part of his revised integration write-up that’s coming next. BuddyPress.org uses deep integration, but it’s still tricky and still has pro’s and con’s, particularly on a shared host and also with xmlrpc requests.
By the time that bbpress turns 1.0, most of the integration issues should be resolved, but you’re still loading ALL of WordPress + bbPress to make things go.
