Moves joining players to the world spawn
Ideal for lobbies, although a proxy is not required

No config, no commands. Just plug it in and start it up

Note: I wrote the wrong title for the 1.16 upload, it is version 0.0.3 despite saying 0.0.1. To download 1.16.5 and 1.17.1, go to version history and click download next to the corresponding version

Permissions:
SpawnOn.bypass
Anyone who has this permission will not be teleported to spawn when joining
