Contact Form 7 is available to PIE users by requesting it from the Publish.illinois.edu team. It allows you to create and customize one or more contact forms for use on your site. (Tech Services strongly recommends that you request and enable the Really Simple Captcha plugin at the same time, for spam management.)
For more information on how to use and customize Contact Form 7, see the Contact Form 7 creator’s website.
