Same here, been loving the beta. They really got the feel of it down compared to Q3. I have a private server that a few of us play on for Q3, ioQuake 3 build for modern system support, orange Smoothie mod for better admin stuff and the updated Quake Live maps (they improved vortex portal significantly by putting the rail gun in the middle of the map for instance).
What I hate about Q:C is all the damn loading, get ready, warmup screens. Seriously get in the game already, stop readying up. Compare that to the current running beta of Unreal Tournament that uses a progressive loading scheme, it's awesome.
