National Novel Writing Month is a month-long challenge to write a 50,000-word novel in November.
The forums are open all year but very quiet. Sign up at www.nanowrimo.org.
Singapore wrote almost five million words in 2009.
National Novel Writing Month is free to all participants. If you can donate to help with the costs that's great. If you can't then take a look at how you can donate when broke http://www.nanowrimo.org/eng/donatingwhenbroke. It really works!
Singapore Chapter has its own NaNoWriMo forum.
