At http://www.missingmanuals.com, you'll find news, articles, and updates to the books in the Missing Manual and Power Hound series.
But the Web site also offers corrections and updates to this book (to see them, click the book's title, then click Errata). In fact, you're invited and encouraged to submit such corrections and updates yourself. In an effort to keep the book as up to date and accurate as possible, each time we print more copies of this book, we'll make any confirmed corrections you've suggested. We'll also note such changes on the Web site, so that you can mark important corrections into your own copy of the book, if you like.
In the meantime, we'd love to hear your own suggestions for new books in the Missing Manual and Power Hound lines. There's a place for that on the Web site, too, as well as a place to sign up for free email notification of new titles in the series.
