Create notification of new users with core Trigger and Action modules

  • Go to admin/config/system/actions and Create an advanced action, selecting Send an e-mail.

    At the bottom are all the tokens available to insert in your text.

    (Note: Not all of these tokens are working / maybe incorrect, maybe buggy: http://drupal.org/node/870868

    Label:
    Send e-mail to administrator for new user

    E-mail:
    admin@example.com

    Subject:
    New user has signed up [user:mail] [author:mail] [user:name]

    Message:
    [user:name] created.

    Mail: [user:mail]

    Then go to Triggers.
