It's nearly that novel-writin' time of year again

If there’s one thing I’ve learned from doing National Novel Writing Month two years running now it’s that not only is it possible to write a (big chunk of a) novel in a month, but that – for me, at least – it’s nearly impossible to do it any other way.
So, yes, I plan to participate in NaNoWriMo again this year. What am I going to write? I have no idea! That’s the best thing about it. On the first of November I will sit down and start writing something and start discovering what it is I *need* to be writing right now.
Anyone else care to join me?
