Check out things before you forward them.

I just received an email from a friend warning me of some dire thing that might happen and alleging that the warning is TRUE!!! Well, before I forward things I always check them out at Snopes.Com, a site where all the various urban legends and other Internet riff-raff are collected and searchable. Sure enough, the warning is 'false' and the background and history of it is laid out so you can judge for yourself.

Don't forward emails unless and until you have checked them out, if only to cut down the traffic on the Internet to a reasonable load for your friends.
