National Novel Writing Month is a challenge, with yourself, to write a novel in a month. The simple rule is to write 50.000 words in the month November. I did it last year and I am considering to do it this year also. But this year I plan to do it on this blog. In that way it is very easy to combine two of my personal challenges. NaNoWriMo of course, and this 365 day blog.
NaNoWriMo should be called iNaNoWriMo if you ask me. There is a very international community writing in November, including a lot from the Netherlands.
