Time travel is practically impossible when you are NOT referring to time zones. If you wanted to go into the future (say, 30 years from now) that would be impossible because the future has yet to exist. And it it impossible to go in the past because it already happened. Think of it like this: You are being chased by a GIANT stone block that you cannot pass behind you. It moves no matter what. The stone is time. You cannot go behind the stone. So you cannot go back in time. Sure, it's just some analogy conjured up by a bored 11-year-old, but that's not the point!!! It's a darn good one! I don't know what's in front of the stone... ah, you are locked onto the stone. You cannot move from your locks.
Anyways, back on topic.
Could you give us this member's name? You could have just misread the joining date or something...
