As a Drupal-oriented company we - AltaGrade team - are happy to be celebrating Drupal's eighteenth birthday and sharing the joy of the founder, Dries Buytaert:
Eighteen years ago today, I released Drupal 1.0.0. What started from humble beginnings has grown into one of the largest Open Source communities in the world. Today, Drupal exists because of its people and the collective effort of thousands of community members. Thank you to everyone who has been and continues to contribute to Drupal.
