Drupal
General features of Drupal
- Friendly - Drupal uses Apache's mod rewrite to enable customizable URLs that are both user and search engine friendly.
- Modules - The Drupal community has contributed many modules which provide functionality that extend Drupal core.
- Open source - The source code of Drupal is freely available under the terms of the GNU General Public License 2 (GPL). Unlike proprietary blogging or content management systems, Drupal's feature set is fully available to extend or customize as needed.
- Personalization - A robust personalization environment is at the core of Drupal. Both the content and the presentation can be individualized based on user-defined preferences.
- Role based permission system - Drupal administrators don't have to tediously setup permissions for each user. Instead, they assign permissions to roles and then group like users into a role group.
- Searching - All content in Drupal is fully indexed and searchable at all times if you take advantage of the built in search module.
