I think a minor because then they would have a little insight as to what they are writing about. If it's someone who didn't aplly then the person could've seen the story but ignored it, right? If it's a member of CRAYONS it'd be totally unfair. They're ALREADY a member and they get to be co-author? I don't think so! Or you could just ride it out yourself. Totally fine. But it'd be easier if you have a co-author. I always have a co-author and they really help me along the way :)
