this datapack adds a queue to the server for each new player. When you first log in, no one can leave the respawn point until the administrator writes the following commands in the chat:
For reomve queue:
/tag @a add not_in_queue
For add queue
/tag @a remove not_in_queue
This datapack is still in the early stages of development, and there may be some flaws in it. I will improve it to perfection in the future.
