Creative world

/mw create NewWorldName Flatland
/mw setflag NewWorldName CreativeWorld True

Import world

If you have old worlds say from Multiverse, when the server is restarted Mulitworld will unload these worlds and not show up in /mw list. Therefore you need to backup your worlds and in game/console do:

/mw create OriginalWorldName

Where OriginalWorldName is the name of the world as it was/is and it will load it from now on and be viewable in /mw list

Ensure the permissions are correct!

.dat files go in data folder
.mca files go in region folder

List worlds

/mvlist
or
/mwlist

Set goto location for world

/mw setspawn

Teleport to another worlds

/goto WorldName
