First off, here's where to download Hamachi (just found it myself): https://secure.logmein.com/products/hamachi/download.asp
(there is a free version and a premium version; the most important difference between the two is that the premium version allows for a lot more than 16 people on one network)
And now: I set up another network (located in the US)
Network: windomXP SP2
EDIT: After noticing some other servers, I've decided that I probably won't be hosting my own server very much. So...send me a message (a PM would be fine) if you want to play.
