I added applications to the group. Birthdays, People Map, and group profile.
There is also Address book, but I disabled it because it is redundant with the
map. You can put your address in the map (if you want to). These are seen only
by this group. I can't figure out how to make the address book come totally
back off! If anyone wants to use it, I can enable it, but I figured the map was
enough - and it is kind of cool to see it geographically.
