I would offer the suggestion that with the number of people volunteering already, it would be "easy" to break things down into the individual chapters, and hand those out for the individual to review/give feedback. It would also increase the amount of work they would be able to do without getting tired/bored, and severely lessen the amount needed to be done by any "chief ed."
Ie. one person could look through Chapter 5 (Domain Actions) and comment on the stuff that was confusing, needed clarification or just felt downright odd, while another had a go at Chapter 6 (armies/warfare), and so on and so forth. If any of the persons finished quickly, and felt like doing more, they could then continue with another chapter as need be, or even be assigned a chapter already under scrutiny by someone else, to put another set of eyes on the matter.
It is really just a matter of coordination, combined with how much the individual feels like contributing.
