Diligence is still under development and incomplete, and some this documentation is wrong. For a more comprehensive but experimental version download the Savory Framework, which was the preview release of Diligence.

Contact Us Feature
This simple feature contains a /web/fragment/ that displays an HTML form with a CAPTCHA that allows users to send a message on a specific notification service channel. System administrators or others subscribing to the channel would then receive it. Straightforward!
Note that a different form is displayed depending on whether the user is logged in. Logged-in users will not have to enter their email address or pass the CAPTCHA. We already know they are legit, by virtue of having logged in!
The originating IP address is included in the email.
