Drupal is the name of the software that powers chasing cacti . There are Drupal web sites all over the world, and many of them share their registration databases so that users may freely log in to any Drupal site using a single Drupal ID.
So please feel free to log in to your account here at chasing cacti with a username from another Drupal site. The format of a Drupal ID is similar to an e-mail address: username@server. An example of a valid Drupal ID is firstname.lastname@example.org.
