How do I set per-world permissions?

Question

I'm using the PermissionsEX plugin on my Bukkit server for command permissions and I would like to make WorldEdit avaliable to all players only on the creative plots world (created with Multiverse), but avaliable to staff anywhere?

Answer 1

It's very simple.

//mind the indentation (trailing spaces)
groups:
    mygroup:
        ...
        permissions:
            // here put the normal permissions (on all worlds)
        worlds:
            worldname: // <- this is the world name (directory name)
                permissions:
                    ...
