A small and simple module that notifies the site admin (at the admin email address) that a user has registered, or that a user is changing their account information. This was necessary to let the admin of the site know when a user has registered so that they can grant certain permissions. This module solved the problem of clients complaining that they did not know when a user was registering. The previous solution was to have the admin constantly monitor the users of the site in the user management section of the admin panel. Now that many of the admins monitor their email religiously, the notify_admin module solved this problem beautifully.
