Double Submission

Because the form is displaying a thank you message on submission (and hiding the physical form), people seem to want to refresh the whole page to see the form again. As a result, your plugin is constantly sending two submissions.

Can you fix this, either by preventing it, or by returning the thank you message inline with a new copy of the form?

We like the plugin, but need this to stop, or we need to use a new form.
