Ok, I've decided to write/explore The Monster of Dewsberry Drink as my NaNoWriMo project. I'm not sure I'll win NaNo this year. I just don't have enough writing time in my schedule to be able to do almost 2,000 words a day. But I'm going to try!
(And yes, Scrivener is every bit as cool as I thought it was, even in the Windows Beta version that doesn't do everything yet.)
My husband has offered to buy me a copy of Scrivener for my birthday, so trying to win doesn't have that extra pressure on me :)
