I did like being able to look at the world map and see concentrations of members, but it certainly would be nice to have a zoomable map...would mean that members might have to be a bit more precise about their locations, though. Didn't that map also have some statistics as to number of builders in a given location?
Maybe we could add some forum headers for group interest/discussion by region? I could see the sheer number of these getting out of hand, though...might become a nightmare for the Admins...
