I'm willing to put up a server for the ChHa 2, though leaving it on all the time might pose a problem. I'll work it out later. Anyway, I have a computer that's running Ubuntu and I'm almost ready to put a dedicated TF2 server on it. I live on the East Coast, so players in the US and UK are pretty much equidistant from me, meaning everyone would have if not good, then decent ping. The offer stands, PM me.
EDIT: This computer may or may not work, I need to fool around with it.
