This is a site that I frequent.
It's TRUTH OR FICTION.COM. Easy enough to use, just click on search, then type in what email you got that you want to know if it's bull or not, and hit enter. It'll come up with links and what not.
Example: I recieved an email today from a coworker saying how many times the number "11" was involved in the attacks on 9/11. I went to truthorfiction.com and typed in "11" (without the quotes) and found out, yes, it was indeed a fluke. I sent him back the link for the site saying it was a hoax and told him not to send me crap like that LOL!
Give it a whirl. Type in the last "forward this to everyone you know or you'll never be happy again" email that you got and see if it's a fluke or not. Remember, key words only, not whole sentances or subject titles.
I was going to post this in the "email" section of the forums, but put it here instead, as it's not an issue, just a "tool" (for lack of a better term) for all those bogus emails out there.
