Okay, I'm putting my stake in the ground: I am going to be participating in NaNoWriMo in November 2012.
For those of you who don't know what NaNo is, I cadged this off their site: National Novel Writing Month is a fun, seat-of-your-pants approach to novel writing. Participants begin writing on November 1. The goal is to write a 50,000-word (approximately 175-page) novel by 11:59:59 PM on November 30. Valuing enthusiasm and perseverance over painstaking craft, NaNoWriMo is a novel-writing program for everyone who has thought fleetingly about writing a novel but has been scared away by the time and effort involved.
