http://forums.bukkit.org/threads/fun-tp ... 718.14897/ I don't know what you could do with this but I think there are many applications to it.
I myself have personally used this in a privately-run local server. While it is fun, I don't believe it has a place here on ECC. It allows you to enchant weapons with stuff such as fire-effect and a "glass shield", the ability to breathe underwater, create tools with the ability to mine out huge areas with few swings, walk on water, create ways to teleport to locations on the map, create hidden doors, even change the time on the server clock. In my opinion, it is just too overpowered for an economy server such as ours.
