About Drupal
Drupal is an open source content management platform licensed under the GPL. Equipped with a powerful blend of features, Drupal can support a variety of websites ranging from personal blogs, corporate brochures and large community-driven websites.
By building on relevant standards and open source technologies, Drupal supports and enhances the potential of the Internet as a medium where diverse and geographically-separated individuals and groups can collectively produce, discuss, and share information and ideas. With a central interest in and focus on communities and collaboration, Drupal's flexibility allows the collaborative production of online information systems and communities.
