Error: 

drupal_mail('taxonomymonitor-notify', $to, $subject, $body);

Correction: 

drupal_mail('taxonomymonitor', 'notice', '$to, $language, $params);
Plus a new function is needed, taxonomymonitor_mail(), as an implementation of hook_mail().

Description of the Error: 

The API of drupal_mail has changed. The code used in the book is for DRUPAL 5.

[Ulrich is correct. The module uses the old function signature. I swear I remember testing this module, though. I will update the downloadable code with the new version. -JV]
