Dear Lumpley,
I live at the bottom of the world, in a little state called Tasmania, and my options for going to cons to play AW and exchange the other playbooks. Now I realise they were all related to various things, and if you want to keep them semi-exclusive to the people who got them that way that's perfectly fine and justified.
I just wanted to mention that I (and apparently a few other people on the forums here, judging from various posts) would be perfectly happy to buy a compilation PDF of the extra classes, because they look like fun, and I am in favour of fun.
Sincerely,
Charlie
