I would like to be able to send an email back to a user after issue collector submission. Since the collector already tracks who is logged in and user profiles contain email addresses most of the data needed is already in the system. I realize this would not work for non-account holders. The hard part would be creating a place in the collector UI where you could use HTML to customize your reply email for each collector.
This is auto-reply feature has also been requested for JIRA in the following tickets. I'm just extending the idea a bit.
Thanks for the consideration. You are all doing great work!
