Mhm. I'm dead. There are all kinds of people from different times here too, not just people from their own futures or pasts. There are people from the 1940's or the 1800's, the year 4,000, or from places that aren't even earth. Worldhopping is when you use a device or magic or some other means to jump from one world to the other. I've got one, so I can go wherever I want unless it's cut off-- and some places are cut off, usually when bad things are happening, like Twinkie's world.
