Hmmmm.......that's good too. We would have to know where each "friend of Susan" lived and put a flag pin on the globe, representing each one, and then figure feasible centrally convienient meeting points, in each region.
Now how do we find out where everone, that would be interested/able to attend, lives without invading their privicy. Maybe a virtual hat could be created into which every one could anonamously throw their city, state, teritory or province and country.
Calling all geeks.
