So, who's to say we don't make this a twice-yearly event: one event around autumn in the southern hemisphere and the other in the autumn of the northern hemisphere, as befits our global community? I think an event like this will be tough to schedule for any one date so why not hold a couple of different events in a couple of different spots?

This gives everyone who wants to do this a chance to join in the fun.

Personally, I wouldn't half mind coming to both events.
