I have a project for a MLM (Multilevel marketing script). I need a Joomla extention where users can create a profile where they log in (almost like facebook), users must be able to update info like email adresses, banking details, paypal info, etc, age,sex etc.

Once a user has created a profile the script must generate a uniqe link for the user almost like an affiliate link which they can send to contacts, the link must take person that clicks on it to the signup page , and when they sign up, they become the first level of the downline. The first user that sent out the link must be able to see in his profile how many members have signed up under him 4 levels deep.

You
level 1: 10 members
level 2: 30 members
level 3: 200 members
level 4: 600 members

Each member that signs up must be able to see their downline when they log into their profile.

On the admin side I want to be able to update the commision a member earns and then the system should distribute the commision to the upline. Theres must also be an option to set the comission percentages and distribution options.
