I'm terrible at it! I started poking at using yWriter today. I've probably put together two or three hundred words of notes on my current project, and I'm uncertain whether or not I've made any progress on organizing the story. I do hope that at least a list of characters names will help.
Sometimes I feel like all of the work involved in making lists of people and places doesn't further the story at all. Still I know I don't want to be using the same name for ten people!
