I have been unable to find someone to code multiplayer for my mod, but I am now halfway through term and so I should be able to do some work on it in a month or so. Sorry for the huge delay, but my degree is far more important than Minecraft.
(Not gonna mention that many people offered to code it for him. >_>)
EDIT: "Not gonna say" changed to "Not gonna mention".
