The goal of this project is to create an extension for Mediawiki which enables registered users to refer other members through a referral link.
For example, a user signs up and then has a personal referral link which he is able to give to others so that they can sign up to the site's wiki.
There should be a count for each user and how many users he referred and also a list of all users and their referrals (preferably in a tree type list)
This should be very easy to code.
Other projects are planned for this site, so possibility for more work on it will be available for the winner, if desired.
