Administrator A user level on a Joomla site that has access to all front-end and back-end capabilities. Administrators is just below super user level.
Template override Template overrides are a way of changing the way Joomla shows something without changing the basic or core Joomla system. A template override is a layout file that is placed in a special subfolder of the template. If found, it will replace the standard layout file for that template.This means that as Joomla is upgraded to new versions you will not have to repeat all the changes you made.
Author A user level on a Joomla site that can write and submit articles. Author has access to functions from the front end only.
