It seems a few photographers created a stock photography co-op.  Has anyone checked them out?

I looked into them a number of years ago. at the time it I dont think was invite only, it cost about au$300 per year but you got 100% commisssion.  I found a couple of people say very hit and miss, some people did well others did not (but then you could say that about any agency). Apparently at the time they were doing a fair bit to promote themselves as a stock agency at least in the australian market.

I put  them in cubestat, not overly inspiring

VERY VERY hit and miss. The guy is smooth talking and talks a lot. The leads you receive are, to say the least, very obscure (we require a photo of Elvis picking his nose while walking his pet Llama type of thing). If you have the shot you could make some bucks but its gonna cost you $300-$400 a year membership to find out.
