According to
this, US Central Time is GMT-5.
If you are living anywhere on that line, then this is your GMT offset.
I am using GMT-7 as the offset calculation here, since that is the greatest difference in hours from my timezone.
7:00am Sunday (GMT+10) translates to 2:00pm Saturday (GMT-7) if I got the calculations right.
Which would be 4:00pm Saturday (GMT-5).
This is just a preliminary estimate of a suitable time, I can move it to night time if all parties prefer.
I will need about a day's advance notice once a time has been confirmed, to go to EBGames and pick up a PS store voucher to pay for a PSN membership.
After that credit card number leak scandal, I don't want to use my credit card with PS Store again.
From an initial test run, I think we all need an active PSN membership to play multiplayer.
