After more than a decade of working with various revisions and editions of this book, I am amazed at the uniform spirit of goodwill and cooperation given me by many people. Without that spirit, this book would not have seen the light of day or continued helping people. My first editor, Ralph “Jake” Warner, showed infinite patience in working with a first-time author. My second editor, Lisa Goldoftas, challenged every punctuation mark and sentence structure while gracefully deferring to my knowledge about the subject. Also at Nolo: Steve Elias designed many of the helpful charts and made a number of editorial suggestions; Adam Stanhope educated me about computers;.
