Messages In a bottle
by Hdstudios
Messages In a bottle lets players write notes into bottles, send them across the real world and read messages other players left on the server.
What it does
A player writes a message into a bottle, and the bottle is uploaded to a global store on the server. Another player can obtain an aged bottle and pull a random message from that store. Server moderation can screen messages before they circulate, and the mod is described as kinda like the time capsules in Subnautica. Messages In a bottle runs on client and server, so the server and every player need it. Its only file is published for NeoForge 1.21.1, under All rights reserved.
Key features
Message bottles
Players compose a message and seal it into a bottle to send it out.
Random message pulls
Aged bottles from the global store return a random message left by another player.
Moderated content
Server moderation can screen messages, so the store is not shown without checks.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
