Awesome, Right I better pull my finger out and get the first part finished.
So just to confirm its a 19:00 to 21:00 G.M.T slot using Hangouts (having the video on/off is entirely up to you) and Roll20 which will be used hopefully to display any maps and handouts found, there will be a Google+ page as well for those who don't want to get a Roll20 account. I will get cracking on a G+ Community page and post up the link here (Sunday afternoon) so you can have a look at what the general plan is and it will have all the links posted up there as well.
So all I really need is some Sixth edition characters who will be in the Boston area in 1920 and are wealthy enough to take a long sabbatical to visit interesting people in interesting countries. And I'm going to make things a little more progressive than stated in the adventure so that female characters will actually be able to do things.
Looking forward to getting some dice rolling.
