Yes, the December Challenge is still happening. I've just decided to post all of the entires at once - when the contest closes. (So far I have entries from Doug, Pumpkinetics, George Fox, and Dan Main.)
I know this is a change from the normal "post as I get 'em" methodology, but there's only a week left to the challenge anyway.
Next time we'll go back to the normal routine...and hopefully pick a contest that will garner a few more entries!
