Take advantage of the Model inheritance provided by polymodel.PolyModel to have Club, School, Sponsor, and Organization actually inherit from the Group Model class, rather than being composed via ReferenceProperties.

Take advantage of the Model inheritance provided by polymodel.PolyModel to have create a class hierarchy rooted at Person. Also, add some missing Role classes, such as Role, (Organization) Mentor, (Club) Member, (School) Student. Make (Organization) Administrator be a Reviewer like Mentor is.

Make use of PolyModel for Works, Documents, etc. Add some (but not all) of the missing Models related to Documents. Refactor site settings to be useful for any "/home" page view. Make the resulting home settings store a reference to the Document, rather than looking up the Document by a hard-code key name. This is to set the stage for Document editing being generic, and then being able to select from some existing documents which one to use as the "/home" static content. This makes it possible to pre-edit several Documents, have them Reviewed, and then quickly change the "/home" page content as a setting, rather than editing the Document in the settings form (though settings forms might still embed the current document into their form for convenience).
