I promised you an update, but what with all the server problems, I've rather run out of time to do something proper.
What I can say is that I think it went pretty well. We didn't quite sell out, but we sold 67 copies of the book. Considering that only about 650-700 people came through the door, and I think many of them went straight to the gaming tables, I think that's a pretty good number to sell.
What was very encouraging was that firstly, people who saw the book seemed to like it as a product and were keen to buy it, and that secondly, from what feedback I've so far received, they're enjoying reading it.
Small acorns and mighty oaks and all that.
Anyway, here's a couple of pictures:
