Rename the title
I added most of your edits to the document.
1) I think Wayne has specific reasons for mentioning K-18 educators in the introduction. I tried changing the sentence to mention K-18 educators, while being inclusive of other groups. 2) We need to decide whether or not we are going to do case study-type tutorials before we can add text to that effect in the Preface.
Ok, I had removed K-18 - but put it back. Re case study-type tutorials - agreed. I assume we can remove the link to "Preface" under "Introduction" on the front page? (or do we still need it for some of the navigation templates?
