Currently, a contributor can create a post and save it unpublished. However, other contributors cannot see the unpublished post. [Another contributor can search Manage Content to find it.]
We would like a role created that is "Contributor Plus". This contributor can view and work on another's contributor's post. This will allow collaborative effort on a post and allow contributors to review posts.
Typically, you'd assign an Editor role to review but our organization only wants the admin to publish posts so Editor role is not an option.
