Re: bbpress plugins – is it possible ?
@aphrodite @DJPaul theasybutton.com had a great tutorial (July 2009 – 42 steps in my notes) integrating bbPress 1.0.2, WPMU 2.8.4a, BuddyPress 1.0.3 which worked perfectly in old testbed but the link goes to 404 page now. I wouldn’t know if the integration would have held up with the code changes in current BP and WP versions.
There’s an older tutorial http://umwblogs.org/wiki/index.php/Integrating_WPMu,_BuddyPress,_and_bbPress which I never tried before but might help you.
As it is, you might want to wait till bbPress-the-plugin version rolls out after bbPress 1.0.3 is released – https://trac.bbpress.org/roadmap.
There’s a premium BuddyPress Global Forums plugin which I am using right now. You have a sitewide forum which integrates with BP’s group forum component or not depending on preference.
Good luck.
