Ive been reading this thread:
How about an area for individual print trades, where somebody could post an offering for a print in trade for another? Trading is a great way to see others prints, and build a collection.
I know about the group exchanges, but it might be a nice enrichment to the site if there was an active area where participants were trading 1 to 1.
I know it could be done through the classifieds section, but I think it would be a richer experience as a forum.
