Our chatroom says 2 members chatting, even when there's only 1 member online.  How can I set it for a correct count.  Also, what is the refresh area to show the count of members in each room.  As it is now, a member has to click on the room name to update the users in that room. 
ie: Lobby (4)
     Discussion (0)

     Tech (2)

 

How can I make sure these rooms quickly update without having to refresh the screen to show the correct count of users in each room.
