Text book again, again, again

Heard back from Focal Press about the text book and it appears that my proposal / idea is a little too vague for them and needs to be more concrete. I therefore reckon I will perhaps re-work the idea so that is something more along the lines of "ProTools for AV Post Production", i.e. making it more of a hands on ProTools training guide, with some supporting theory. I need to get my a**s in gear and have another go.... being a bit lazy at the moment.
