Require Referral

[Zaiaku]

I've been loking on the forum for a script that during registration requires the person to state their referral.

I found this but it doesnt work: https://vborg.vbsupport.ru/showthread.php?t=60186

And I need this for the lastest vbulletin.

I guess no one ever figured this one out?
