Thanks Laine
Quick update - I've made zero progress in the last week and a half. My toddler had bronchitis and a stomach bug at the same time...

I decided that writing while half-asleep may provide some extra-creative material, but perhaps cause some continuity issues.
But now that I've at least partially emerged from the Swamp of Disparity, I'll get a proper list together, make sure I have email addresses to send the material to, and get my butt into gear to finish this thing. Thanks again for the generous offers of help, folks
