General Options > Registration Profile Fields & Options > Edit a Custom Field > Field Required*
It says under Field Required:
If yes, only Users/Members will be "required" to enter this field.
* Administrators are exempt from this requirement.
I understand my misinterpretation of this now that is means everything registering for an account other than admin will be required to check it but it doesn't require it when I test.
While you are correct, the custom check box works and is visible, when I test the box by registering a new profile, the check box is there and I can click it, however, I am able to register the new account WITHOUT checking it.
I want it set-up so that a new registration can only be submitted if the box is checked.
