I tried NaNoWriMo last year (and failed because of poor planning). But I still have my book folder in EN with characters, plot, etc. I should move the writing there as well. It was pretty terrible and i was quite proud of what I had so far!
I'm curious... one of my biggest challenges has been figuring out how to fit tagging into my crafty projects/notebooks (How do I keep from having a million different tags?). Do you also use tags or simply rely on the note copy for finding things?
