This is a follow-up to an earlier question from 2014: P&T Contact Form plugin: How can I copy “name” and “email address” in the body of the mail? ... it seems that Craft (and the plugin) has gone through significant updates since that question was answered.
How would I include
fromEmail into the body of the message?
I read about events in the documentation, but it doesn't say where they go. Do I put those into the craft>config>contactform.php file? How would I setup an event to handle that inclusion?
