The Symbiostock theme has an amazing idea behind it by using the network between photographers and a nice structure, unfortunately the developer stopped or postponed the project.
while leo is not as active right now, symbiostock itself is just fine -- the theme is stable and doesn t need a coder on call. the install process is smooth & straightforward. I've set up several sites in the co-op in the last coupla weeks where the photographer only needs to be concerned with uploading & editing images.
