System plugins operate every time a page on your site loads. They control such things as your URLS, whether users can check a "remember me" box on the login module, and whether caching is enabled.  New in 1.6 is the redirect plugin that with the redirect component assist you in managing changes in URLs.

Default on:

• Remember me Help
• SEF Help
• Debug Help

Default off:

• Cache Help
• Log Help
• Redirect Help

The core values are:

• Freedom
• Equality

In our vision, we see:

• People publishing and collaborating in their communities and around the world
• Software that is free, secure, and high-quality
• A community that is enjoyable and rewarding to participate in
• People around the world using their preferred languages
• A project that acts autonomously
• A project that is socially responsible
• A project dedicated to maintaining the trust of its users

There are millions of users around the world and thousands of people who contribute to the Joomla! Project. They work in three main groups: the Production Working Group, responsible for everything that goes into software and documentation; the Community Working Group, responsible for creating a nurturing the community; and Open Source Matters, the non profit organization responsible for managing legal, financial and organizational issues.

Joomla! is a free and open source project, which uses the GNU General Public License version 2 or later.

Joomla! means All Together, and it is a community of people all working and having fun together that makes Joomla! possible. Thousands of people each year participate in the Joomla! community, and we hope you will be one of them.

People with all kinds of skills, of all skill levels and from around the world are welcome to join in. Participate in the Joomla.org family of websites (the forum is a great place to start). Come to a Joomla! event. Join or start a Joomla! Users Group. Whether you are a developer, site administrator, designer, end user or fan, there are ways for you to participate and contribute.

If you are an experienced Joomla! 1.5 user, 1.6 will seem very familiar. There are new templates and improved user interfaces, but most functionality is the same. The biggest changes are improved access control (ACL) and nested categories.
