One response per user
Sometimes it would be useful to limit responses to one per user. For instance, as I write this we are using NWC to take a survey of all employees (or at least those who will respond), and it would be nice if NWC could prevent a user from submitting more than one survey. I don't have reason to suspect this will happen, but still it would be nice to have the option. Our previous forms software had this capability.

Thanks a lot for the suggestion. We would like to open this for feedback from other users.

I currently have a use case in which it would be nice if there was a setting in NWC to prevent users from submitting a form more than once. Our previous forms software had this ability. I wish NWC did too.
