A Noob question about Multiple worlds/Multiverse

[speedwell68]

Yes, its possible.
Cuberite has an inbuilt multiworld system. You just need to add the worlds to settings.ini and use /portal <worldname> to move there (and /spawn to get to new word spawn).
Then you can use some plugin like Essentials and add warps/portals to all worlds.
The only problem I can see are the inventories, there are no per world inventories.

Thanks. I will take a look at that.
