I am assuming that all four of the user names with some variation on "simply it" are all you. If that is the case, I would like to point you at rule number 14 of the constitution which says, in short, "Pick a name and stick with it." It can get confusing for people trying to talk to you. Worse yet, confusion leads to annoyance, annoyance leads to anger, anger leads to hate, and hate, as we know, is the path to something or other. You know what I mean.

So, please, stick to one user name in the future.

If I created a mini(Oxegen), can I keep it? If you misspell the name of a gas, who knows what creature could be spawned from it.

Ooh, a mini! Anyways, the Disc runs off Narrativium and million-to-on e chances. The reason is pretty much 'Don't think about it.'

Besides, THEY think that our spherical world is weird ( how do the people on the bottom not fall off?) so yeah.

But in Strada, an earlier Pratchett work also featuring a disc-shaped world, there's a teleportation mechanism teleporting water back on-world, IIRC.
