I think, This is a listing of FT'ers stays in Marriott's. So if you like to meet any of them, you can see if any of your travel plans coincide with others and plan accordingly.

From what I read until now FT'ers sometime have seminars/training/get-together(s) /meetings and many of them know each other in the off-line world ( a.k.a - the real one )

I haven't had any chance to meet any FT'ers until now, but I am hoping some time in future.
