I'm looking for a membership / referral / affiliate plug-in that makes a WordPress site a viral promotion machine..
So in this plug-in, new user would automatically be affiliates, with a unique user ID -- http://your-site.com/aff/?id=89
Alternative have the possibility to send emails to potential new members, and if the new user click on the URL provided, this would be registered.
That way you could advertise giveaways / run promotions based on user id's
