I think the best way to go would be to partner with a magazine (photovision, black and white, lenswork, for example). The magazine would then take a big submission from APUG say once a year, then publish a yearly "The Annual APUG Portfolio". Who knows, maybe it would gain a cult following and be the 'sport's illustrated swimsuit edition' of photography? We would need to make sure the timing is right for this, maybe the site is still too young?
