Drupal 5 module which posts to twitter a link to each created or updated story node. To use, rename twitter.inc.php.txt to twitter.inc.php and edit it to change your_username and your_password.
You should work with http://drupal.org/project/twitter and post patches there. The Drupal.org Twitter module kicks this module's ass.
