I'm aware of a couple of problems, which are down to this not being created by Adobe; it doesn't display properly in OS-X preview (use Acrobat), there are no links to chapters, and page 35 (which has a lot of sideways text) displays sideways and prints upside down! This will be sorted before the final release. I hope...
Anyway, it's come out as 92 pages with 49 pages pf actual gaming material - the rest is Abbott's book. It's a 2.8 MB download, and I'm thinking of asking $4.99 for it; comments on pricing would be appreciated, bearing in mind that the goal is to make money for charity.
