dom3minions has preset games, I think Gandalf adds new ones when there are no slots left. Most games, though, are PBEM on llamaserver. It's fairly easy to setup. You should probably start a thread proposing a new game there or look up for starting games or games looking for a permanent sub.
You might also want to hang out on the IRC. I hear some games are started from there and you can get feedback fast there.
And of course: welcome.
