this is an unexpected twist to photographic assignments. I'm wondering why is it limited to SF only? I mean, there shouldn't be a limitation from a technical point of view. Do you plan to extend it?

This is an interesting idea. My concern is what about the people whose submissions don’t get picked? They wasted time for nothing. Is there a limit to how many people can sign up for a job?

Also, you’d need mechanisms in place to stop people from downloading the pictures and paying no-one.
