Go to Yahoo and/or Google and create an email address there. Use these for people who you do not trust. You will probably need to change your home email address and then only give that out to people you trust. If you or someone in your family enters online contests, that is a good way to get spam. When filling out forms, always uncheck the boxes that suggest sending you promotion materials or special offers. I always remove all of the names from forwarded emails if I am forwarding it to someone else. Make sure your real email never appears online in any newsgroups, forums or auction sites. It only takes once for the spamming to begin if you are not careful.
