You can use your TivTag to invite your friends once you have completed 5 Quests. Then, once your friend signs up using your TivTag and they've completed 5 Quests, you'll automatically receive 500 points from the referral!
If you've been referred to Tiv by your friend, make sure to put their TivTag under "Invite Code (Optional)" on the sign up screen. This is important, as invite codes cannot be added after the account has been created.
