I'm going to be setting up a very large WP install. There are going to be 12 sections of the website. Within each section there will be several people who will be able to edit the content.
What I want is for each of the sections to have a section manager who will do the initial approval of the content. Once they've approved it, it will then go to the next level of approval (one of 4 or 5 people) who will then approve and make the updates go live. This group of 4 or 5 will approve everything for the site, not just one specific section.
I want to also ensure that these people who can edit and create content within their section can ONLY create content in their section, and not anywhere else.
So, can this be done? If so, what are the steps needed to do so?
