If I went back in time with a computer, the computer is being powered by a generator, and the computer was on this page (we all know that if the internet disconnects we stay on the same page), I go back one day, would:
One: The site database say my post was ever there??
Two: My post be here.
Three: What if I pushed the modify button??

Also, when I say 'My Post' I mean this one.
