I have regretfully given up on this after finding another e-mail from my agent's office suggesting that my mss. are unacceptable to Smashwords in their current (already corrected several times) format. The instructions for changes do not deal with terms I understand. Furthermore, the formatting destroys title page appearance (like caps, larger fonts, and centering), makes it impossible to center chapter titles, objects to more than 3 or 4 paragraph breaks per page (that also affects title pages), objects to setting poetry apart by indenting or centering. And what is Dashboard? Text box?
I should add that I use the tab key a lot to indent. It has become a habit.
The Kindle project may still be alive. That is in the hands of someone else.
Initial reports suggested that the formatting can be achieved in about 2 hours. I've already spent at least 20 hours on this. I assume that the time quoted does not include struggling with the instructions.
Life's too short.
