Project Technology: RedHen

RedHen CRM is a Drupal-based lightweight CRM that provides a set of CRM buiding blocks developed with native Drupal components. It provides a good toolset for sites that integrate with external data systems (such as SalesForce), but it also provides a good starting point for CRMs that need to take full advantage of the flexibility of Drupal's advanced site-building features (such as Views, and Rules).
