Looks like there has been some movement in the bbPress world which I am happy to report: WordPress integration!
If you’re looking to integrate bbPress and WordPress, life just got a little easier.
Setting $bb->wp_table_prefix in bbPress’s config.php will tell bbPress to grab users and user meta data from those WordPress tables.
The CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE constants are still around and will override other settings if you need more fine grained control.
They also added in cookie, registration and function integration. It is great to see it advancing again. Check out bbPress for your bulletin board needs.
