Re: bbpress activity not coming though
@arturo84 – Use BuddyPress’ own insert activity function – bp_activity_add() available in /bp-activity.php as either a bbPress plugin or a code snippet in your bbPress theme’s functions.php.
You’ll need to hook into the right actions in bbPress. You’ll probably want to hook it to when a new topic is created and when a new reply is made. I don’t have these actions at the top of my head, but this should give you enough to go on.
Something I forgot to mention is if you’re using your bbPress install in conjunction with BP’s group forums, you’ll probably also want to omit posts that belong in the group forum’s category ID, which in most cases is category ID #1. Why? Because you might get duplicate forum post entries in the activity stream.
