All in, 10 spots remain, quickly folks!
I think the best way to try and arrange this is to set a time that hopefully everyone can make (or a couple of times)
I recommend leaving up to half an hour available for each game, as some games can take that long, although I've found two player speed tends to get itself over pretty quickly. One person or another dominates early on. Hence the best of 3.
In retrospect, I don't think running games simultaneously is a good idea... I'll make them all available, but I suggest you play them one at a time (of course, this is up to individual pairs, and should be discussed amongst yourselves before you join your games).
I envision each game will remain unjoined untill both players have confirmed they are ready. Then both join, and play.
For the timing issue, I will spilt everyone into an A or B division based on which time they prefer.
I also think weekend times will be easier for most people (I know they will for me) so we will set GMT - Noon (sat day) and GMT - Midnight (Sat night) as Division A and B playing times. (If you can arrange to play your games other times than these that's fine but they will be the "preset" game times, hopefully starting next weekend if we get players by then)
Just a few quick convesions
GMT Noon | London 1pm | 8am NY | 5am LA | 10pm Sydney | 8pm Perth
GMT Midnight | London 1am | 8pm New York | 5pm Los Angeles | 10am(sun) Sydney | 8am(sun) Perth
If you could edit your posts to tell me whether you want to be in division A or B that will make my life a lot easier

Cheers folks! Look forward to getting this started soon!
