I would love to see some sort of group video chat with one or more chatrooms within the main  "chat room". Something that would be very easy for members to join into like to click a join button or enter the main room to use it then once inside members can join other chat rooms from within the main chat room. Maybe on the basic idea of the old Dolphin chat but better. Also to give the admin the ability to configure this chat to the needs of their members.
