Drupal is a free software package that allows an individual, a community of users, or an enterprise to easily publish, manage and organize a wide variety of content on a website. Hundreds of thousands of people and organizations are using Drupal to power an endless variety of web sites.
Dave Hall Consulting has contributed patches to several Drupal contrib modules, including drush, date and YUI editor modules. DHC has regularly provided support and engaged in discussions on various drupal IRC channels and we attend the Melbourne Drupal meetup.
