Joomla is an open source content management system referred by tens of thousands as the best CMS in the world.
Once installed, the website administrator can login to the backend administration console and set up sections, categories, content items, polls and much more; administrating the entire frontend of the website from a point and click interface. When new content is created, a WYSIWYG (What You See Is What You Get) editor allows for simple edits without the knowledge of HTML. While it is not mandatory the user have knowledge of HTML, it is recommended to engage in a few HTML primers in the event that something needs to be edited on a more custom level. The Joomla community forums are available with thousands of programmers and designers to help new and advanced users when possible.
