Anyone playing World in Conflict?

Ended up buying it this weekend. Fry's had it on sale for thirty bucks. I bought the "Collector's Edition," which came with a purported piece of the Berlin Wall...

I thought it was kinda funny that the singleplayer opened with the Soviets invading Seattle. I can see the parking lot I was fighting in outside my window! Then they blew up the on-ramp I take to work everyday. Definitely a little weird.

Anyway, I've played enough that I'm ready to try multiplayer. I tried to sign up as an AK member, but it said the name was taken. Has anyone around here registered us?
