This useful plugin solves the problem of constant spam in chat when players earn achievements. A special game rule blocks notifications about new achievements that usually interfere with communication and take up a lot of space in chat.
Main advantages of using NoAnnounce include reducing chat spam on the server and increasing player privacy. Now players can complete achievements privately without notifying all server participants.
