If you invite a friend to Tracklib that's not already a user, the person invited will get a 30 day free trial, with 15 free download credits. Once they've signed up and after their free trial, once they're on a paid subscription, you'll get 10 free download credits which you can use to purchase any 10 tracks for free.
You can invite as many friends as you like, and each of their signups will earn you 10 track credits.
Remember to tell your friend to use the signup-link with your invite key. Just copy the link from your referral page which can be found by clicking on your profile in the top right corner and then use the drop-down menu to select "Referrals". From here you can also automatically share your referral link on your Twitter and/or Facebook.
If you have any questions or issues, please contact email@example.com.
