I love this idea. I tend to randomly bounce between working on ideas for one of the movies, get distracted by life or some other idea or something, forget about the previous ideas, start working on ideas for a different edit, etc. (Kind of like how I kept up with watching and giving feedback for your TCW edits for a while, then got distracted and still haven’t gotten to catching up…) This could better channel that energy into something collaborative.
A month is a good length of time for each subject, I think; it’d keep discussion fresh. I’d certainly try to contribute, at least.
