Registered     - can see non-public parts of the web site

Author           - can create new (unpublished) articles.  cannot edit any articles

Editor            - can create and edit any articles. cannot publish/unpublish

Publisher       - can create, edit, organize (by existing section/category) and publish/unpublish on the frontend

 

Note: none of the above user types can log into the backend!

 

Manager            - like Publisher but can login to the backend and manage site structure like menu/section/category/article

Administrator     - can manipulate users

Super-Admin     - can do anything possible in Joomla, including uninstall components...

 

That's what I've learned and one question I have is: I don't see an obvious way to restrict Author-through-Publisher to some subset of sections and/or categories.  I'd think this would be fundamental to the scheme...

 

Thanks for reading!
