I sent a message to Shaun asking what was happening with the Reptile Classifieds site and only got a vague answer like he's been away from the computer, did not know and would check?
The structure and functionality of RCA was good except perhaps the photos were too small when viewed on a computer and APS is better in that regard. No idea of the economics of running such a site but APS exists now so any revenue from advertising etc must be a bonus to the existing cost structure, RCA charged for a variety of things including bumps and I am sure breeders will be happy with something similar.
