An invitation to the world how a guest

[xyaran1]

What problem does this feature solve?

For example, the world has rights like "worlds.name " but I don't want to make it freely available. But I want the player to be able to teleport into the world if he is invited as a guest without access to the worldedit.

For example, "/tpa nick" and in case of a response from the owner "/tpaccept", the player can teleport to a private world. And also, if the Owner writes "/tphere nick", the player too teleported into the world as a guest.
