Here is my web-use tip: www.bugmenot.com. I love this site.
Ever notice how many web pages request your e-mail address and various other bits of demographic information? Afraid that they're going to use your e-mail address to send newsletters or ads? Don't want to answer what zip code you live in? All this just to look at an article that was linked from another site?
Bugmenot.com is the answer. Go to the site and enter the domain name you need an ID for and they will give IDs and passwords that could work instead of registering yourself. Try it!
