IMPOSSIBLE to move on my secondWorld

[NiLSPACE]

In the settings.ini in the [Worlds] section add

World=<WorldName>

For example:

DefaultWorld=World
World=World2
World=World3

You would now have 3 worlds. One is called "World" and it is the starter world, and World2 and World3 where you can only come using /portal or another plugin that allows you to change worlds.
