When assigning roles to a forum for posting or viewing, you're only able to select assigned subscriber groups to these roles. I would like to also have an option to assign these to other non-subscriber 'access' groups that exist within a world, including Owner, Authors, Editors, and Followers. This would make it trivial to set up forums for, i.e., announcements (Only owners and authors can post, but everyone can see), a staff forum for coordination directly on the website instead of through a third party app, etc.
