Joomla is the most popular Content Management System. It is much more than just a powerful content management system. Besides, hundreds of extensions to enhance functionality of any Joomla website, Joomla itself includes some powerful built-in features (or core features).
#1 Content Management
Joomla's simplified three-tiered system of articles makes organizing the content a snap. The content can be organized in any way. Website users can rate articles, e-mail them to a friend, or automatically save a PDF. Administrators can archive content for safekeeping, hiding it from site visitors. On public Web sites, built-in e-mail cloaking protects email addresses from spambots.
Creating content is simple with the WYSIWYG (What You See Is What You Get) editor, giving even novice users the ability to combine text, images and formatting in an attractive way. There are a number of pre-installed modules to show the most popular articles, latest new items, newsflashes, related articles, and much more.
#2 User Management
Joomla has a built-in registration system that allows users to configure personal options. There are multiple user groups with various types of permissions on what users are allowed to access, edit, publish and administrate. Authentication is an important part of user management and Joomla support multiple protocols, including LDAP, OpenID, and even Google mail. This allows users to use their existing account information to streamline the registration process.
#3 Media Manager
The Media Manager is the tool for easily managing media (image and others) files or folders. The Media Manager is integrated into the Article Editor tool to grab images and other files at any time.
#4 Contact Management
The Contact Manager helps users to find the right person and their contact information. It also supports multiple contact forms going to specific individuals as well as groups.
#5 Banner Management
It's easy to set up banners on Joomla powered web site using the Banner Manager, starting with creating a client profile. After adding campaigns and banners, impression numbers, special URLs and more can be pre-set.
Joomla's search feature helps navigate users to most popular search items and provide the admin with search statistics.
#7 Web Links
Providing link resources for site users is simple and can be sorted into categories, and even count every click.
With Joomla, it is very easy to syndicate site content, allowing users to subscribe to new content in their favorite RSS reader. It's equally easy to integrate RSS feeds from other sources and aggregate them all on the website.
#9 Menu Manager
The Menu Manager allows to create as many menus and menu items as you need. You can structure your menu hierarchy (and nested menu items) completely independent of the content structure. Put one menu in multiple places and in any style you want; use rollovers, dropdown, flyouts and just about any other navigation system you can think of.
#10 Template Management
Templates in Joomla are a powerful way to make the site look exactly the way you want and either use a single template for the entire site or a separate template for each site section. It is very simple to change the look of the website without distorting the content structure.
