Ben Forta

Thanks to my co-authors, Charlie Arehart, Jeff Bouley, Ray Camden, Sarge, Robi Sen, Matt Tatum, and Jeff Tapper, for their outstanding contributions. Although these books are affectionately known to thousands as “the Ben Forta books,” they are, in truth, as much theirs as mine. Thanks to Nancy Ruenzel and the crew at Peachpit for allowing me the creative freedom to build these books as I see fit. Thanks to Wendy Sharp for stepping in as acquisitions editor on this revision and to Judy Ziajka for so ably shepherding this book through the publication process (without her we’d still be struggling through Volume 1). Thanks to Nicholas Tunney for his through and insightful technical editing. Thanks to Damon Cooper, Tom Jordahl, ...
