NIAD, or 'Novel in a Day' is run by Pigfender over at literatureandlatte.com. They developed Scrivener and Scapple, but you're not obliged to use them.
I've written a chapter for four, so far, and had hysterically weird and fun days at it.
I have no idea what the genre is this year, but the first time I took part it was a Western.
NaNoWriMo (also big fun) takes a month, this is a day - a mere bagatelle.
Check it out!
