I have put Chs 1-4 in Feedback,
http://www.odfauthors.org/libreoffice/english/impress-guide/feedback-lo3.4
I can't recall for sure, but I think Chapter 1 was ready to publish.
Chapters 2 includes Hazel's edits. She had sent the file to me after
her problem with the disappearing images. I have restored the images.
I think this chapter is now ready to publish.
Chapters 3 and 4 have comments, suggestions, and some edits by me
(with change tracking on) in them. I didn't go through them in great
detail, but it looks like you have made some significant improvements.
Thanks!
I am now looking at Getting Started with Impress.
