Minimum Age?

Which plugin are you using?
you may need to use javascript to validate the field prior to submitting it.

I am not using a plugin, I am using the basic BuddyPress>Users>Profile fields..is there anyway that I can make it stop at 18 years old? Like today it would be 13/11/1994, tomorrow 14/11/1994 and so on..

Thanks for the support!
