Age Restricted Registration?

[Stepahnie123]

Is there anyway I can force people to supply their date of birth BEFORE they register? I don't want to see their passport or anything like that, just a date to be typed in.

I'd like to make sure all my members are 21+ and if they are under 21, can their registration automatically be cancelled?

I know I could manually allow registrations, but I'm looking for an automated way to do this. I'm just wary that minors could sign up and that would not be appropriate.

Thank you,

Steph
