Drupal is an open-source content management system (CMS) which helps you maintain and update your website in an easy, hassle-free manner, be it:

• Community web portal
• Discussion site
• Corporate web site
• Intranet application
• Personal web site or blog
• Aficionado site
• E-commerce application
• Resource directorie
• Social Networking site

For two years in a row (2007, 2008) Drupal was ranked #1 open source CMS in the world and it's been ranked #1 Best Open Source PHP CMS in 2009. While there are a number of alternative software packages and frameworks to build your website in, Drupal has earned a reputation of a flexible and multi-task CMS that enables an untrained PC user to update and edit any web content in WYSIWYG mode (what You See Is What You Get).
