Advanced content editing workflow in WordPress through the use of section editing groups and permissions.
In order for a user to be added to a section group they must first be assigned a role that is limited to section editing capabilities. The plugin comes with one such role – “Section Editor”. Any user you would like to add to section editing groups must first have their role changed to section editor. It is also possible to use a role management plugin (such as Members) to create your own “section editing”-ready roles.
For more information on creating roles for use with section editing groups, see the Github Wiki page.
