Dear Amy: What's the best search engine to use?--Darren, Minneapolis Dear Darren: Each of the major search engines gathers and organizes Web sites in different ways. Unfortunately, even the search engines such as Searchopolis at www.searchopolis.com for kids might contain stuff your parents may not want you to see, so be sure to ask permission before you search. Use Yahoo! at http:// yahoo.com if you want to look at broad categories and then click through the subcategories to find what you want. If you are looking for something specific, like a computer store, then go to Alta Vista at www.altavista.com. If you are not sure how to start, you can Ask Jeeves at www.ask.com. (The first site is no longer available.)
Dear Amy: I've been looking all over for a place to make a Web page. Please help!--Neal, Lexington, Ky.Dear Neal: If your own Internet Service Provider doesn't give you free server space, you may want to check out The Free Site at www.thefreesite.com to look for a free server site. They list the sites with a description of what each one offers. Some of them require you to put banner ads on your page or limit the size of your site. Ask your parents to help you make the right choice; then write me when you get your page going.
