Sorry all, apparently the offer to GM was for just a solo run, and it was 11PM (which would be 1AM for me), so unfortunately that won't work (thanks very much to John L, regardless)! However, since there seems to be a lot of interest in this kind of thing, I'm going to put together a game that I can run as a one-shot or as an ongoing campaign with people who join and leave and re-join at their convenience. I'll try to have it ready ASAP, possibly by next weekend.
