This is my 6th year doing NaNoWriMo, and as an ML. So yes, I'm knee-deep in NaNoing goodness right now! This year, I'm pushing on with Book 3 of Starwalker, hoping to finish off this arc of the serial.
This year, I'm being extra-ambitious: I'm organising a writer's retreat for the last weekend of November. Heading off to an island resort (just off the east coast of Australia) with about 30 writers all doing NaNo. It's going to be insane. (It's already nuts, and that's just the logistics!)
MCA: you get 1 free book through CreateSpace if you win. I haven't heard that they've increased it to 5, but that's not impossible. But it has been 1 book for the past couple of years.
You also get a 50% voucher for Scrivener for winning!
I'm Kess there too. Good luck, fellow NaNoers!
