I am using jquery.validate.js by bassistance, I have some question regarding the date validation. I am developing a website that has registration, what I want is to filter the age of the user who wants to register, allowing only 13 years old and above. If the user typed a date that is in the bracket of 13-17 years old he or she needs to check a checkbox for parental consent, and if 18 and above no need to validate if check box has been check.
