This mod is a fairly complex mod, which allows the user to make a Message in a bottle. These can be uploaded to a global server, and then someone else on their world can obtain an aged bottle, this will pull a random message from the server (messages that other players have sent) to be read. (kinda like subnauticas time capsules)
I can see all messages on the server, and moderation will be done if necessary.
