How do you reset a world in everybody edits?

You type in on the chat bar "/reset" which makes all the people go back to the spawn points or start.

OR you type in on the chat bar "/loadlevel" which makes everybody go back and resets your level to when you last saved it (including the coins come back if you have collected them)

However if you don't have chat you just press "enter" on your keyboard to make the chat box come up then type in the commands "/reset" or "/loadlevel"
