End Users (cont.)


Super
-
administrator (SA):


SA is the one who created during the initial Joomla
installation, under the account name

admin



Act as the king of the web site, therefore having

no restrictions on the system


Similar to

root


of Linux


Depending on the user

s group designation, the administrator
interface will appear differently


Ex
: The interfaces for the lower
-
level groups (e.g. manager)
are missing many of the buttons and menu items that are
present when an SA is logged into the system

Manager


It a mechanism for preventing conflicts of two users
trying to make changes to the same document



When an article is being edited, it is automatically
checked out to the user, and no other user can edit it
until it

So, this feature will automatically checks in all items
that are currently checked out
