I want to know if there is a way to still keep a normal global default rank but at the same time have a world have a different default rank? I've tried to do so but am not sure if this would be the correct code:

  F:
    prefix: '&f[&cF&f]'
    permissions:
    - essentials.warps.f
    worlds:
      Prison:
        default: true

Thanks!

I think it might actually be possibly to set a group as default in only one world. While a group itself is global, the data within it can be restricted by world. You'd want to just set the default option to true in the appropriate world.

Isn't the setting

options:
  default: true

only for groups?

That can't be put under the worlds: section of a group, can it @zml2008 (for PEX 1.x or 2.x)?

    worlds:
      FirstWorld:
        options:
          default: true
        permissions:
        - modifyworld.*
      SecondWorld:
        permissions:
        - modifyworld.*

I thought what he was asking for was "everyone on the server to be in the group 'aaaaa', but on the world 'Prison', everyone on the server is in the group 'bbbbb'."

World-specific groups may be a function of PEX 2.0 (don't quote me on that; I have no experience with that version), but they're definitely not part of PEX 1.x versions.

Users are members of groups, not members of worlds. Keep in mind that with global and multiworld permissions, you can completely control who can do what on which world.
