so what does creuk mean?

I was thinking the same thing...however, the following thoughts pop in my head which bring me to think otherwise:

The word "radio" is in the url already, so that would be redundant.

He's not anywhere near the UK because he lives in Washington State. I know his old domain had the .uk in it and I asked him before about it. I guess it was a cost/availability thing that christianradio.com was unavailable or something.

Don't get me wrong, I'm not picking on the guy. I just was wondering what creuk meant.
