Good News Today.
I rewrote Chapter 6 as the publisher suggested and submitted it to the publisher. This afternoon I got this reply.
"Many thanks for sending me through your final PDF. We’ve now been able to look through the PDF and it looks like it has taken shape very nicely, and it is great to see the inclusion of more step-by-step photographic sequences, which I think work very well. It’s great to hear that you will soon be able to submit everything."
So now we will move to the next stage.
