Referral System for RevCMS?

[VicemTete]

Hey there! I'm using RevCms and just wondered if a referral system can be added because i really need it.
Does anyone have some codes? No exploits please.

I guess that's not around yet...

I can try to make it but I don't know how you exactly want the system to be and how you want it to function so I may just have to ask that first.
