SS has always been my highest earnings site but total exclusivity for RF doesn't appeal to me. It would have to be an amazing deal to get my interest. It would take a lot of time to remove my portfolio from all the sites I use. Then there's the risk that SS could be sold, like istock was.
Aren't they going to do the sensible thing and have image exclusivity instead of contributor exclusivity? If they go for contributor exclusivity, it could end up a choice between SS and istock. I like selling with several different sites and don't want to be given that limited choice. I would be so shocked if they went for total exclusivity, it just doesn't make sense now.
bigger portfolios are always hard to deal but in the end the return on agencies is more important, that said I wouldn´t go exclusive unless it is a really nice deal once I have "wasted" much time on many agencies some taking months to get payouts, it is all a question of numbers but being dependent on an agency doesn´t attract me..
