eh eh 
I’m using Kirby to manage a photography magazine that you can see up and running on magazine.landscapestories.net.
We invite photographers, we select project and the final ones are showcased on a specific issue.
Usually the authors are sending project by mail, and after the selection, I setup the folder for each project and manually update the content.
I’m wondering if it will be possibile to create an account for each author, so that he/she can update his/her works, adding the captions and so on. In this way, it will be easy for me to publish only selected project and hide the ones that we rejected.
I know that kirbycms has also roles and permissions and I’m experimenting this on my local dev in order to give each author access to their projects (authors can be published more than once, and on different issue number).
