Have you ever had an affiliate program used with Matukio that rewards users for selling tickets to events. If you are aware of a 3rd Party extension that has been successfully used before with your system please could you provide us the details.
This would be a fantastic (and virtually unique) element that would set Matukio apart from the competition if you were to develop something like that...just a thought
I think the only Event program that offers this is Eventbrite.
