I am a participant in NaNoWriMo every year (except for last year when I was too lazy) and every year I have a great time with it.
I've actually only "won" it twice, in 2003 and 2004 but I've been participating since 2001.
For those who are not familiar with it, it stands for National Novel Writing Month, and during the month of November, the goal is to author a novel with 50,000 words in the thirty days. And the motto? No plot...no problem.
I will probably not get a lot of reading done. But I will get a lot of writing done.
I'll post my progress occasionally, here.
