Collection of Date of Birth/Use as variable

Client has a requirement to check the date of birth of registrants and then either not allow registration (<16) or allow registration but with a text warning display (16-18).

Looking through the forums a number of customers have asked about Date of Birth validation.

Wishlist:
1. Be able to collect a date as the date of birth.
2. Be able to test the value of the DoB against the event date (The event date needs to be made available to test against)

If anyone is interested I can share my custom solution which is inelegant but uses an ajax validation.

Hello,
I am interested in your solution. Can you send me your solution?

Hi,
we setup a date field with the following validattion:

validate[required,custom[date],past[1998-11-13]]

Couldn't get the event date so had to be hard coded.
