“It’s the activity stream, stupid.“
I have been following BuddyPress almost since its inception. I love the “DIY” feel and accessibility that aligns it so well with WordPress. I thoroughly report bugs whenever I can. I like the BP Forums (bbPress) core component, and have created a few plugins for BP Forums, including one “Move Topic” plugin already available in the WP Plugin Repository, and some “new posts since last visit” that I haven’t gotten around to uploading yet (you can find the code by searching these forums, or bug me to upload it to wordpress.org).
