Amnesty for open source sites
As pointed out in an email from Dan Macquillan of Internet Artizans, Amnesty International’s website is now running on the open source platforms of Drupal and CiviCRM.
I’ll add it to the CharityBlog link page of open source use by voluntary groups, but it’s getting such a common occurrence now that a) it would be difficult to keep track of them all and b) it’s no longer hard to find and learn from such examples.
