[Plugin: WordPress Form Manager] Email sent to unregistered users?

Great form – but I’d love to be able to have an email notification sent to the form filler.

Appears that this can only be done for registered users (which is not where we want to go as we want anyone to be able to submit a form and get notification without registering first).

Is it possible for an unregistered user to recieve an email notification?
