when u click on navigate, u see that map,
and differient colors, but i should add a color:
for exp. blue when a friend of u is living at that zip code,
bcause otherwise u could search for houres by kliking evry zip code to see a blue house.
... People, if you click Status *Its right next to Chatrooms, which is next to Navigate* and then click on the Friends tab, you'll be able to see who on your friendslist is online, where they are in Towns and if the have a home in Towns.
