BuddyPress.org

First, I just found a small bug and fixed it in the trunk – you just need to update the file: bp-forum-extras-activity.php

Second, make sure you add the theme edit (detailed on forum extras wp-admin page)

The comments appear directly underneath the post which has the activity. It pulls in all replies for the given post (so threaded). It will work for any backdated activity comments – whatever it can find for the given group_id and post_id (item_id)
