IP detection is crap, too. I'm in California and while my IP sometimes gets detected as being from a few towns over, it's certainly still in the United States - but I'm blocked.
Same problem. I'm in Hungary but that doesn't make me Hungarian, and my business is based in Indiana. If you want to appeal to this crowd you'd better be prepared to think a little harder about internationality.
Fair enough: nobody can accuse you of not being responsive :)
Add a +1... Had to log in to my computer via LogMeIn to request an invite. Currently traveling in Nicaragua, but I'm a California resident.
