An OSTraining member has asked us how to achieve the following in Drupal 7:

1. A customer fills out a form to send their request for repair or service on a specific piece of equipment.
2. A customer service agent comments on the request to either approve or deny it.
3. The customer gets an automatic email after his request has been processed.

In this tutorial, you will look at this use case. You will learn how to achieve these requirements by creating a node.
