So far the hardest time coordination is England to West Coast US. That doesn't sound too bad if the West Coasters are willing to play in the mid to late morning and our European friends are willing to play in the early evening.
I've checked the instructions on Skype. To do it, everyone has to be on Skype and a central person has to build a group. Search me on Skype if you like. I used my real name, which is Derek Zurfluh. Send me a message with your Skype name and also your Chordie 'handle' so that I'll know who you are. How funny that we know one another's handles and consider the real names the "who-dats".
