@KemoNine @paulfree14 @Curator @Ayior @Jennahos If we don't mind low res exchanges, they can just toot it to the next person.
If we want to work with high res files, mediagoblin as suggested, or a nextcloud install somewhere might be the easiest.
(also, do we have a sign-up? do we have people nominate invite ad-hoc, or maybe have a pile of outcomes for people to pick for next day?).
