Affiliate Marketing Secrets

For starters, I’m a first year NaNovelist, so I’m not that familiar with it’s inner workings.
The site is completely swamped right now and I can’t even get it to load on my computer, so I’m asking my question here in hopes that someone affiliated with the site will see it. Anyway, I read on a blog somewhere that in the past they gave whoever won NaNoWriMo a free copy of their book. Anyone know if they’re still doing that?
Also, are people participating allowed to post what they’ve written online anywhere? Or is it required that the whole novel be finished before released to the public?
If anyone could answer it would be greatly appreciated, and whoever is taking part this year I wish you all the luck in the world!
Cheers!
