From the developers of WordPress comes new forum software called bbPress. Not only is this great news for people who just need forum software, this is awesome news for those who also use WordPress because of user integration. Still not convinced WordPress can function as a lightweight, fast CMS? bbPress is a huge step, in my opinion, to choose WordPress for CMS projects because it is fast, easy to maintain, there are lots of plugins to add functionality, and now you have a forum/bulletin board that is secure and ties in with your WordPress blog/site user base. Great work guys!
