So it seemed natural to expand the lessons into a manual.
It was too short, just barely, for a standard book. Plus I doubt I have the reputation to get a book on writing to a major publisher.
A third consideration is that considering the lag time between submission and publishing, even if I was very lucky it wouldn't be out to readers for two years.
30 sales in less than 48 hours. It may actually have an ISBN soon.
It's a whole new world.
