bbPress.org

That’s the best setup for integration, with the bbPress directory a subdirectory of the WordPress directory. The thing that threw me was that this is still a valid (if somewhat broken) URL:

I think the integration needs to happen up front, in the config.php, since an integrated install modifies the wp_users table and does not create a bb_users table. I’m not sure if you can go back and edit the config to make it integrated later. I don’t think it would work since the table creation and modification are done upon installation.
