1. What machine has a fulcrum?
Dear Beverlye: When you first start out, the Internet seems totally vast. But don't worry. Usually, your Internet Service Provider will help get you started with the right software and teach you how to connect with the World Wide Web. From there, it's just type in the URL (the funny address of Web pages) and click on the underlined words or hot links. A good starting place for you might be www.seniornet.org. Have fun!
Dear Amy: I was on chat and gave my e-mail out to one person. Now I am worried. Can people track down where you live based on e-mail?-Sara, Annapolis, MD
Dear Sara: Kids should not give out their e-mail address to anyone without their parents' permission. If you are worried about it or if someone has sent you e-mail you don't like, you should tell your parents right away. It's possible to find out people's names through online directories, but by being cautious and telling your folks about it you shouldn't have anything to worry about.
