I know that you are busy with the book but you are also the moderator, I think? Maybe I'm wrong and you aren't. It seems to me that the message board is, oh, I don't know, becoming a little loose and uncontrolled. It all reads as very random and unfocussed. I feel that it may need your input. Forgive me, if I sound intrusive, but it isn't as it was.
Hope the book is going well - good for you for doing it!
