Multiplayer

Multiplayer Minecraft was released officially on the 8th June 2009, after many beta trials. Users can download and run the server package that allows other players to connect to and play on their server. Future versions will have multiple Game Modes. The wiki sidebar has a link to the Minecraft.net server list. Redstone Wire Ltd also hosts a Minecraft server list.

Community spirit
In multiplayer, players can press 'T' to chat to others. Multiplayer nurtures the community spirit; people work together to build things, and unite in the face of griefers. It is the strong policing of these rooms, powered by a "patriotic" attachment to the game, (or one's favorite server) that makes the game very hard for griefers.

Technical
The server saves the level to the server_level.dat file every minute.
