[rich! @ etiviti]

are you trying to display the recent activity in the group directory, underneath their info?

I just wrote a Quick Tip about this on my demo site

http://etivite.com/groups/buddypress/forum/topic/quick-tip-display-the-groups-recent-activity-on-group-directory-groups-loop/#topic

includes the source code and the call to feed_item_title()

with the method i outlined you can add in the new_forum_posts to only show that activity
