Experimental project

This is a sandbox project, which contains experimental code for developer use only.

This module adds a required Phone Number field to the built-in site-wide Contact form provided by Drupal.
It adds the field just below the sender's name.
The resulting phone number is appended to the email that goes to the site admin.
There is no admin interface - it just does what it does.

I believe someone else is working on a broader effort to make Contact form fieldable, so I probably won't be doing much with this beyond what's here.
See https://drupal.org/project/contact_field if you're interested in that project.
