Dedication This is for Suleiman. Authors Acknowledgments This is my eighth For Dummies book and, as always, the experience of writing it has been productive and fun. Thanks so much to editors Tim Gallan, Christy Pingleton, Lindsay Lefevere, Shira Fass, and Suzanne Langebartels for setting me right as needed. And thanks to the folks at Borderlands Caf on Valencia Street in San Francisco for the friendly, peaceful, and caffeine-accessible environment that virtually any writer (this one, for example) would find conducive to putting actual words on paper.
