I'm getting a lot more out of my NaNo experience this year. I've figured out basically how Scrivener works (awesome writing program, btw), I know what I'll be working on and have some plot points already sketched out, and I'm even more active on the messageboard this year.
There are two swaps that I'm involved in, a Tea Swap with a woman in the US, and a Goodie Swap with a woman in Australia! Fun! I'd love to participate in the local write-ins, but my laptop is in the boneyard, so maybe next year. I would like to take the train and attend the Night of Writing Dangerously in San Francisco sometime. I hear a lot of craziness goes on during that event.
