This tutorial explains the different user types in Joomla
By default there are four user groups in Joomla: Registered, Author, Editor and Publisher. Each group allows certain access to parts of the Joomla interface
We are currently logged in using an account with Editor access
Registered users cannot edit articles, Authors can create and edit their own articles, Editors can create and edit other users articles, and Publishers can do all of the above in addition to being able to change publishing status, start and end dates for any article
Scroll down and notice that the articles are displayed with icons for editing each individual article or to denote an article is currently locked
1) Let’s select an article to edit by clicking on the edit icon for that article
Now scroll down to access all the editing tools for the current article
Logged in as a user with Editor access, you can edit other peoples articles, but you do not have access to change the publishing status of articles. Only Category, Author’s Alias and the access level for the current article
If we log out as an Editor and login as a Publisher, we can see the additional available options presented to us
Logged in as a Publisher, we can now change the Status of individual articles from Published to Unpublished or visa versa, establish Start or Finish Publishing dates, as well as all other editing features
Now you have an overview of the different types of users in Joomla
