Sometimes people say that playing on anarchy servers far away from spawn is like singleplayer with chat, so this mod just makes the exact thing possible.
CAUTION
When you connect to a server from singleplayer, you phisically connect to the server with the account you are on. Otherwise chatting wouldn't be possible. Make sure the account you use in singleplayer is in a safe location on the server.
In addition, I do not take any responsiblity if you get banned from a server while using this.
This mod uses MCProtocolLib, which can be found here
