I would like to participate. What size prints are needed? Should they be mounted? How about describing the process a bit more; I'm new here so I'm not sure how this is supposed to work.
I'm new here too, but from the links supplied this is what I understand...

Any size prints
Any style of print
Mounted or unmounted is up to you
(Just give something out that you would be happy to get)

All the participants are divided into groups of 6 maximum. Each person sends 1 print to each person in their group. All the other group members send out their prints as well... You send out 5 of yours and you get 5 from others.

The groups are randomly picked.

Am I wrong?
