I'm currently on a mission to build an efficient AS flash website, and this book has been the most helpful by far for helping me on my quest. Before this book, I struggled through spotty references and pulled my hair out while waiting to get responses to my questions that were posted via online forums. I now have it sitting on my desk and it is filled with post-it notes, highlights and dog-eared pages. Everything flows in a logical order, yet you can still flip to different chapters to follow different exercises and not get lost. I especially love the downloaded examples and lessons... there is no greater way to learn. A quote by Lee Brimlow on the cover states that this book is "The best ActionScript book ever written," and I think that pretty much sums it up. Great job Rick and Zevan!
