Instead of building a new website by starting with a vanilla installation of Drupal, a not-for-profit organization could save much time and money by starting with a Drupal "distribution", which is a single installable package that contains the core Drupal code along with contributed and custom modules, appropriate configuration settings, and a theme, or some combination thereof — basically a generic prebuilt website for a particular purpose or category. There are more than a thousand such distributions available, and many of them are intended for nonprofit organizations, including Open Outreach (for community organizations), OpenChurch (religious institutions), OpenPublic (governments), and Drupal Commons (collaborative communities, such as Drupal Camps).
