In high school, Margaret Levine Young was in a computer club before there were high school computer clubs. She stayed in the field throughout college, graduated from Yale, and went on to become one of the first PC managers in the early 1980s at Columbia Pictures, where she rode the elevator with big stars whose names she wouldn't dream of dropping here. Since then, Margy has co-authored more than 25 computer books about the topics of the Internet, UNIX, WordPerfect, Microsoft Access, and (stab from the past) PC-File and Javelin, including Access 2003 All-in-One Desk Reference For Dummies, Dummies 101: The Internet For Windows 98, UNIX For Dummies, and WordPerfect for Linux For Dummies (all published by Wiley Publishing, Inc.), Poor Richard's Building Online Communities (published by Top Floor Publishing), and Windows XP: The Complete Reference and Internet: The Complete Reference (published by Osborne/McGraw-Hill). Aside from explaining computers to anyone who will listen, her other passion is her children, along with music, Unitarian Universalism (www.uua.org), reading, and anything to do with eating. She lives in Vermont (see www.gurus.com/margy for some scenery). David C. Kay is a writer, engineer, artist, and naturalist, combining disparate occupations with the same effectiveness as his favorite business establishment, Acton Muffler, Brake, and Ice Cream (now defunct). Dave has written or contributed to more than a dozen computer books, including various editions of WordPerfect 11 For Dummies, Graphics File Formats, and The Complete Reference, Millennium Edition. Besides writing computer books, Dave consults and writes for high-tech firms, and also teaches about wildlife and edible plants. For recreation, he paints theatrical sets, makes strange blobs from molten glass, sings Gilbert and Sullivan choruses in public, and hikes in whatever mountains he can get to. He longs for the Rocky Mountains of Canada, pines for the fjords of New Zealand, and dreams of tracking kiwis and hedgehogs in Wanaka. He feels silly writing about himself in the third person like this and will stop now. Richard Wagner is an experienced For Dummies author whose writings span both technical and non-technical worlds. His tech books include WordPerfect 11 For Dummies, XML All-in-One Desk Reference For Dummies, XSLT For Dummies, as well as 15 other computer books. He also invented and architected the award-winning NetObjects ScriptBuilder software product. In his non-tech life, Richard is author of Christianity For Dummies and Christian Prayer For Dummies and editor of the Digitalwalk.com e-zine.
