Haha, referrals are when you post the link that is in your control panel, to a site owned by you, or Myspace, or anywhere else on the internet. When a person clicks the link it will take them to the home-page, then they click on register and once they sign up you get a referral.
By referring friends, neighbors, or others to the site, you earn points! Referrals can be acquired by visiting either the Link-to-Us page or by copying and pasting the link given in your profile settings. Referral points are only rewarded after the user clicks the link and signs up for an account. Any abuse found in creating multiple accounts to earn points will result in a ban from the website.
Taken straight from the help site. Please refer there, or to a moderator, for answers to these quiestions, rather than making a thread about them. Thank you.
