This year I'm going to do something I've never done before - I'm going to write an outline before I start. The last time I checked, it was allowed as long as you don't actually start writing the story. I'm doing this in hopes that it will turn out to be more than just a month-long writing exercise.
If you want to friend me on Nanowrimo, my name is marlabowie. (Also, I'm still deactivated on Facebook, so if you get a friend request from me, it's bogus. I do check in to make sure my account is staying secure.)
