Adding/ Editing list of people with photos I've created a content type called 'Cast'. Authorized users need to have ability to create a different list of cast members, add/edit their info, upload photo. Essentially, it's a team roster problem.

I'm having hard time figuring out how to solve this problem? What module is most suitable for this purpose?
You can do it using Drupal Core itself with out using any module. Just follow below steps to solve the problem.


Login as Super Admin
Go to admin/people/permissions/roles
Add a new role called "Cast Manager"
Give Edit any and Create new "Cast"  Content Type permission to "Cast Manager" role in admin/people/permissions/roles


That's it ! Now, users who have "Cast Manager" role can edit any cast content and manage them !
