From the NaNoWriMo website:
National Novel Writing Month (NaNoWriMo) is a fun, seat-of-your-pants approach to creative writing.
On November 1, participants begin working towards the goal of writing a 50,000-word novel by 11:59 PM on November 30.
Valuing enthusiasm, determination, and a deadline, NaNoWriMo is for anyone who has ever thought about writing a novel.
