I'm looking at CB for a new project.
We need to completely block/stop the registration process based on a data field during registration.
The field is the 'birthdate' field.
If the user enters a date that is less than 16 years ago, we need to completely block the registration from proceeding (with an on-screen notice). We can not save any data for the user (for legal purposes).
Is there any way to do that within CB (native or with add-ons)?
