Well, I've been in DivineChaos for a while. I don't have any authority to invite or whatever, but I'm sure I can at least talk about it. We're fairly active, and like to do stuff. Our teamwork ain't too bad, I can attest to that. We're a pretty intense guild from time to time, and way too relaxed at other times. We had a mock battle a little while ago where we all used different general souls and tried to keep it up as we fought. Playing as Zhen Ji was never more fun, especially since you can become "suddenly not a general" mid-combo...
One of the big things is that we use Ventrilo. If you don't have any problems with that, I'm sure you'll fit right in. We use it for everything, and we'll bug you to get in so we can form parties, yell about lag, laugh, and make plans on the fly.
Here's a website
. You can register for the forum there, post in the recruitment thread, and let stuff happen. I dunno how it works, I joined the old fashioned way (ran into the leader in the tavern). You could take that route too, just ask an officer or our leader, ZhaoYun.MC1, in game.
