Write a novel in a month?

If you've always thought you might have it in you, here's some incentive. NaNoWriMo:

National Novel Writing Month is a fun, seat-of-your-pants approach to novel writing. Participants begin writing November 1. The goal is to write a 175-page (50,000-word) novel by midnight, November 30. [snip] Because of the limited writing window, the ONLY thing that matters in NaNoWriMo is output. It's all about quantity, not quality. The kamikaze approach forces you to lower your expectations, take risks, and write on the fly.

Not just in the U.S.
