We had to make a few educated guesses about you, our audience, when we started writing this book. Perhaps your computer is solely for personal use—e-mail, the Internet, and so on. Or you might run a small business or work for a giant corporation. After taking these quite varied possibilities into account, we assumed that you’d be familiar with computer basics—the keyboard and your little friend the mouse, for example—and that you’re connected to the Internet and/or a company intranet. We also assumed, if you’re working on a corporate network, that you’re familiar with the specialized and customized tools, such as a SharePoint site or a file-management system, that are being used on the network. We also assumed that you’re using and that you’re familiar with the basics of Windows Vista, and that you have the Aero glass appearance enabled. However, if you’re running Microsoft Windows XP, you’ll still be able to use this book, although you might find that the look and function of the windows and dialog boxes on your screen are a bit different from those shown in this book. Whichever version of Windows you’re using, we’d like to recommend two other books we’ve written that you’ll find helpful: Windows Vista Plain & Simple and Microsoft Windows XP Plain & Simple—2^nd Edition.
