NaNo is simply crafting with words instead of paints, glue, cloth or whatever your preferred medium
Indeed it is... although I can't imagine how many swap points a NaNo novel would be worth!
As for everybody who is already planning or having ideas - how DO you do it? I'm definitely a pantser, as anything more than the most basic idea of what I want to happen seems to take all the wind out of my sails. I guess for me the month is as much about discovering the story as it is about putting it down on the page.
