redanman,
As MJFay also said, when you know you're going NC, just leave the course. We don't know how many chose this route.
And, if I am understanding something else he said, if you are someone who 'should' be there you'll probably stay no matter how much ink you've used, take the inevitable ribbing, and forget about it.
I think you should see the thing through, for better or worse, but you don't deserve the label of poor sport if you don't,
maybe wuss, but not poor sport. If you decide to 'take my ball and go home' it has little to no effect on the remaining field.
