What I would like to do is. When a customer refers a friend, the friend puts in the friends email or some other "code" for the friend that referred them to the site. If the friend that was referred buys a product, then the friend that did the referring gets the points.

So, I'll try to make it easier to understand:

If Jim referred Mike to my site and Mike signed up and inputed Jim's "code". Then when Mike bought a product, Jim would get the points.

Then when Jim gets enough points, he can redeem them for products.

The only way I am able to do this now, is manually keeping an eye on who refers who and if the referred buys something, keep note. I was wondering if the site could do this, if a mod was available.

Thanks for any info!
