Navigate to your Freedom! Dashboard. When logged in you'll find your profile picture there and right below it you can find your Referral link. It'll look like this:
Code:
https://freedom.tm/via/georgevanousfanclub
(of course it'll have your name after the /via/, this is just an example)
When someone joins using this link you'll receive 50% of what they'll earn for a year.
NOTE that referred channels make the same amount of money and that the 50% come from Freedom!. When a channel you've referred earns 50c you get 25c and they still get 50c.
Also please don't go out of your way to recruit users by sending out emails etc.
