Right, since this is one of the new games doing the rounds I figured I'd make a post about who has it and stuff.
It seems that to even play
on my server or host your own, you need to have your firewall off, and a bunch of ports open. Take a look here
for more information on that.
If everyone has those ports totally open and stuff, we should have no problems playing together. I've tested it with a couple of people now, and having those ports open is definitely what makes the difference between it working and not working.
Just contact me on msn (email@example.com) or IRC if you want me to slap up my server so you can test connecting to it and stuff. Whee.
