No Customer Referral in my Zencart

Hi, I have just launched my Zencart and now need to create a customer referral program. I cannot find it anywhere. I looked through the forum and it is nowhere to be found. I looked in the EXTRAS tab in the admin panel but it only shows: Record Artists, Record Companies, Music Genre, Media Manager and
Media Types.
Does anyone have any advice on how to add the customer referral program? In short, i need something to track sales and give sales commissions, since I will be getting other companies to advertise our products and would like them to get a commission on any customers that came through them.
Advice greatly appreciated.

Not sure if this is what you're looking for but what I did is to enable customer referral status on
Configuration -> Customer Details -> Customer Referral Status -> 2

When a customer creates an account they're asked: Were You Referred to Us? Referral Code:

They enter the person's first or last name, or other code you pre assign.

Then I can run a Customer's Referral Report under Reports in Admin and see how many orders have been placed under each.

Hope this helps, if not, I'm sure that someone more knowledgeable will come to the rescue.
