National Novel Writing Month (which gets shortened to NaNoWriMo, for reasons I find utterly incomprehensible) has been moved to April this year. That means it's time to get started. Check the NaNoWriMo site for help, advice, and tools to track your progress -- or, if you're the sort of person who prefers to do things on their own, just started writing! Can you finish your novel in a month?
Ready... set... go!
