You may or may not have heard of this before or maybe somebody has posted about him, but there is was a man claiming to be from the future a little while back. He went by the name John Titor. My gut-reaction to this was BULLSHIT, but after overviewing everything that he said.... things that he predicted in 2001 have came true in 2003-2004. I have a neutral oppinion about it but i no longer remain skeptic. You can find information about him at:
In one of these sites they have archived posts that he has made.
