The mod adds a redesigned chat system, essential for large servers, with a division into global and local, and also reimagines the communication system using unique letter systems.
Chats & Letters
Local chat
Local chat works within a radius (64 blocks by default) of the player. The /me (action) command works the same way.
Global chat
Global chat works across the entire map, and by default, it requires a letter, which the player must have in their inventory to send. It works similarly.
Letters
One letter is required to send one global or private message in chat. This significantly changes the gameplay, forcing players to write more thoughtfully and increasing the value of paper. This feature can be disabled!
Commands
Mute system:
/mute <player> GLOBAL/ALL hours
/unmute <player>
/mute list
Block system (blacklist):
/block <player>
/unblock <player>
Offline letter:
/mail send
/mail read
