Website database advise

[Ghoulish Delight]

I wasn't actually suggesting vB as the solution, just using an example I know well to illustrate how it's possible to "dumb down" an otherwise overpowered solution to fit your needs.

The question for the csv/xl file solution would be, how is that file generated? Do you already have a database with the referral information being tracked? If so, you may be able to cut that step out and just have that database export directly into the reward point soultion.
