well, for us in North America it might be better starting at 5 30 GMT as it'd be around midnight for most of us... but then, it's a little unfair on our Brittish counterparts (Wait, will this hamper Saucepan Wolf? hmmmm
) Anyway, I cast my vote for 8 GMT. North Americans may have to vote a few hours early but it would give Brittish (And most European I guess) people a chance to vote before the deadline.
I must admit to be ignorant of Timezones in Europe though, so those of you who actually live there should speak up now or hold your peace for ever.... or 'till the end of the current WW game, whichever happens first
