Thanks, Stefano!
Where can I edit the code that drives the data validation for the widget? What file(s) do I need to access? My plan is to rework the existing functionality to utilize JavaScript popups only. I feel the user experience would be more consistent that way, although ultimately I would like to implement an ajax-driven solution when time permits – something similar to Contact Form 7.
Thanks again. I appreciate your help and your awesome plugin!
