Is there a way to require input into a field (such as the "Enter Additional Comments" field shown below) within the site review request form? We need to prompt the users for particular information before they click on submit. If they don't provide something in the field they won't be able to submit the request.
It should be a simple HTML form element which you can modify from the template editor. I have not tested it right now but you should be able to simply add an "required" attribute to that field. See details here:
