Hey Kymac, first off welcome to the forums. A few of us play but not too many. I'm not even sure if we still have a server. I just bought the game last weekend and suck so bad that I'm only playing on easy and I believe our server is normal. HeatSurge is our resident Killing Floor expert. I'm sure when he sees this he will be able to fill you in.
Edit:
Yes, we still have a server. It's listed right on our front page. I guess I should pay attention.
