Permissions

Each rank has it's own set of 'abilities' constrained between them, such as the ability to rename the world, to change the thumbnail, etc. For example, a player with the "Admin" permission level can access both Admin and lower permission level features. The owner of the world can create custom permissions with custom abilities.

A player who has been banned from a world will be shown with this rank in the player list and will not have access to that world unless they are unbanned.
