I would like to have an Invite Friends function through a personal URL.

So users don't have to fill email addresses and sand them an invitation but copy a personal URL and post that link as an invitation in a message on Facebook or anywhere online.

And have Easy Social track which new users get registered through which user invitation. I want users to gain point if they actively invite friends and promote my site.

The standard Invite Friends is nice but can not be integrated with other social media and cannot go viral like a Facebook Post or Tweet can.
