I know I am getting to this late but the print exchange I was in did it this way. There was an address list that was published and if there were 10 people on the list you make 9 prints and at some predetermined date the 9 prints get mailed to the addresses on the list and then everyone is covered and can keep the prints to do with as they please within the laws of copyright law. At some future date then the list can talk about the photos they received. Sort of a critque.
Any interest in doing it that way????
