About the Author
Doug Lowehas written a whole bunch of computer books, including more
than 35 For Dummiesbooks, among them Networking For Dummies, 7th
Edition, Java All-in-One Desk Reference For Dummies, PowerPoint 2003 For
Dummies, and Word 2003 All-in-One Desk Reference For Dummies. He lives in
sunny Fresno, California, where the motto is “No, we aren’t really the Armpit
of California,” with his wife, the youngest of his three daughters, and a goofy-
looking six-month-old Shar-Pei/Black Lab mix named Lucy. He’s one of those
obsessive-compulsive decorating nuts who puts up tens of thousands of
lights at Christmas and creates computer-controlled Halloween decorations
that rival Disney’s Haunted Mansion. Last year he actually built a pirate ship
in his backyard.

Author’s Acknowledgments
I’d like to start by thanking everyone who was involved with the second edi-
tion of this book, especially project editor Christopher Morris, who heeded
the Hitchhiker’s Guidecreed (“Don’t panic!”) when I was occasionally late with
submissions and who did a great job following through on all the little edito-
rial details needed to put a book of this scope together on time. Thanks also
to Dan DiNicolo, who gave the manuscript a thorough review and offered
many excellent suggestions for improvements, and to copy editors Jean
Rogers and Andy Hollandbeck, who whipped my prose into shape, crossing
all the i’s and dotting all the t’s, or something like that. And, as always, thanks
to all the behind-the-scenes people who chipped in with help I’m not even
aware of.
