Ninja Forms is a great WordPress plugin and this plugin makes it even greater!
If you’re using Ninja Forms for gathering data and one or more of textbox fields
must be unique, this plugin is for you. The plugin is pretty straightforward to
install, and has few settings only (language settings, basically).
Once installed, it will validate every submission to make sure the values for
one or more fields are unique.
