Thanks for the plugin - using a standard setup and the widget (not form builder) and like the simplicity of everything.
One issue I've noticed though - and it seems to have been raised by a few people in the forum without getting resolved - is that form fields don't seem to get validated/verified. So even if I submit the form (first-, lastname and email) without adding any details at all, I still get a thanks-form-submitted message. No user is obviously registered in the CC list, as there were no details.
Is there any chance that form validation could be added? Seems like a useful function to have.
