Ah, I remember watching the Month of the Novel last year sometime, probably it got brought up last November. At your mention of it, I watched it again, and it was fun seeing the comments on the HW chat room. Ah, the good old days.
I was reading your progress thread for
The Invasion, which I had apparently missed seeing until now, and your story-crafting process sounds similar to mine.

Which is to say, constant re-vamping of the whole thing. But it sounds like you're on a good track (which is really more than I can say for several of my stories). As you haven't posted an update on there since September, may I ask where you are at right now?
Meanwhile, on the day when I told myself I would actually start writing for my Nano project, I took approximately two hours to decide on names for all of my characters and locations and to figure out the precise set up to the beginning of the story. Now that that's done, let's hope that tomorrow I actually get to the writing?
