Thanks so much for the response so far. There seems to be a pretty big need for an exchange like this, and we want to do it right.

jenn_calaelen are still working out the kinks in rules, the schedule, and how sign ups will work.
Keep brainstorming: we're reading your ideas, organizing them and trying to make this the best exchange possible! Thanks for your patience.
