I have posted a bunch of FAQs on the Piracity campaign page (go here, scroll to the bottom).

The most important stuff is about the size of the final book, and how the money will be used. As I say in the FAQ, the plan is for 18 stories of not more than 7,000 words. If everyone maxes out that’s 126,000 words, which is a pretty substantial book. I haven’t made that a specific campaign promise because a whole variety of factors may prevent us from doing exactly that. As for the money, most of it will go to pay the authors, printers and Kickstarter. We’ll need a cover, and I want to pay Roz and Jo as well. I’m not going to get any money until the project makes a profit, which I doubt will happen until well after publication.
