5 or 6?
Yoshimaster (Anime North a few times), GTM (my place and his a few times), TRE (AN twice), also Nio (Japan & Malaysia), and SantaRPG (stayed with him a few weeks after coming back from Japan)
the "or 6" is that I've been in the same room as ff6man at AN, StreetPassed him even, but we didn't actually meet
