I deleted a number of the topics you posted. Those were all questions that a quick look in the TOC or the Amazon book page would have answered. We're grateful that authors spend time here answering questions, and dispensing some of their expertise. We'd much prefer if they didn't have to deal with questions that everyone can look up the answer to in a matter of seconds on their own.

Yeah. Sometimes, in their zeal to win a book, people forget that their posts are to be answered by real people. It would be better to think of the purpose of the promotion as having a chance to speak to the author. Winning a book should be secondary.
