Sorry for all the questions. What I am trying to do, is implement a nearby_checkins in the regular activity feed. So I see you are using a filter places_around for places. I would like to implement the same feature in the activity feed. I see the function where you search the lat and long + and - 4. Then I see in bp_activity_add_filter_options where you add Activity Checkins and Place checkins to the list of options in the regular activity feeds. So I inserted a new one there nearby checkins. What I am having trouble with is finding where it goes next. So where would I insert that function to return the nearby checkins. I am still getting my head around the whole buddypress way of doing things.
