Well we are (a group of friends) trying to get one of us to host a server, but currently we are only looking for a private server.
We might host a public one later depending on what goes on with the game.
Edit: I can host a server for all of you on this computer. But it won't be dedicated and might have some lag since I will be using it also.
If you are interested I can try to host if for sometime, but I don't keep the computer on for ever ^_^ so the server's uptime isn't going to be guaranteed.
