Many thanks to those who have provided technical knowledge, feedback, and support throughout the conceiving and writing of this book. My colleagues at Caliente Media Center and the University of New Mexico, and the Girl Geeks, have all offered critiques and suggestions. Those wonderful, anonymous programmers at Macromedia have provided an invaluable learning laboratory in the files of Dreamweaver itself. The community of extension authors has also been a great source of information and good examples. And my thanks to the editors at New Riders, for believing in this project and helping make it the best it can be.
