A chat will hopefully start at around the following time on Saturday (or Sunday morning if you're down under)....
USA - 3pm PDT / 4pm MDT / 5pm CDT / 6pm EDT
UK - 11pm BST
Australia - 6am AWST / 8am AEST
I hope those time conversions are right, please correct me if they're not.
The chat will probably last a couple of hours, or longer if it's going well. If you find yourself alone in the chat room, it's worth waiting to see if anyone else arrives - otherwise things can never get started!
Hope some of you can make it.
