Features:

• Organize and Find: Drupal comes with many tools to help you organize, structure, find and re-use your content. Categorize with taxonomy, automatically create friendly path urls, create custom lists, associate content with other content on your site, and create smart defaults for content creators.
• Creative Content: Drupal's flexibility handles countless content types including video, text, blog, podcasts, and polls with robust user management, menu handling, real-time statistics and optional revision control.
• Administer: Drupal comes with great options for new user accounts and user permissions. Users can be assigned one or more roles, and each role can be set up with fine-grained permissions allowing users view and create only what the administrator permits.
• Collaborate: Drupal's focus on social publishing can help you create sites and applications to help your users express their opinions and engage with one another. You can have tight control over who can create, view, administer, publish and otherwise interact with content on your site.
• Design and Display: Drupal's presentation layer allows designers to create highly usable, interactive experiences that engage users and increase traffic. Use an existing Drupal theme for your site or try designing your own.
• Extend: With more than 6000 available modules, the vast majority of your site's requirements can be addressed with Drupal core and available add-on modules.
• Connect: Drupal makes it easy to connect your website to other sites and services across the web, using aggregation, feeds, and search engine connection capabilities. Social networking integration is also widely supported to help you engage with a wider audience.
