I think this is a lovely idea - I'd thought about offering a sort of private exchange myself, but am faced with so much Stuff between now and Christmas that I didn't think I'd be able to fulfill even story-writing obligations, let alone organising something. Somehow I've always managed it with MTYG, but this year there are all sorts of extra pressures from my life in general.

Good luck, and I'll be first in line to send feedback!
