I am setting up a collecting form using the Collecting module. I currently have the user email field required and would like to automatically send a confirmation email to the user every time they complete a submission. Is there a way to do this? By default, the “email me my submission” field is visible and unchecked. My first thought was to make it checked and invisible, but after some digging I was unable to get that to work. Is this a viable solution? If so, how would I implement it?
