In along with Davids idea of allowing the customer to change the referral.
I would think it would be best to be able to change the referral in Admin area. I was going to try to add a drop down box so that an admin can Correct or add a referral to the customer record from there.
This would be helpful say if a referral was selected wrong when they signed up, or if you have previous customers like David that you need to now assign referrals to.
I took like this contribution and thanks to you's who worked hard on creating and modifying it.

I am having similar problems. All the products get uploaded to the database, I can see them there. When I go to Categorie/Products after that, they are not showing. I went line by line through the categories.php and can not see that problem.
