Today a member can invite a friend through the website. When this is done and the friend logs in, a statistic is being updated allowing you to see how many refferals a member has - you can also see, how many of those friends has become a paying member.

I would like to connect a payment system to that feature, so that I can pay different provision to the member if the friend creates a profile (fixed amount), becomes a member (% of membership cost). I believe this feature can help to expand the site quicker - having in mind also the expensive promotions with Google Adds.
