Email validation

Vote:
 

Hi Guys, 

I have an issue: I am looking for a way that someone can only fill in a form just once and based on emailadress. So if you fill in a form that you have already filled in in the past, you are receiving an error (this emailadres already exists for example). 

Is it possible to validate on emailadress if someone filled in the form already?

Yes! :-)

Have a look at the documentation for custom for actors, and notice that you are able to cancel a form submission and display an error message.
