Referrals must be made through your unique referral link. Any referrals made outside of this link will not be counted as they cannot be tracked. Kickstarters system for tracking referrals isn't perfect, so make sure those following the link have used the advice we sent you when supplying the code as this gives them the best chance of being logged.
Referral rewards are only available to backers of tiers higher than the value of the total reward - because of Kickstarter's referral terms we can't give you a reward higher than the value of your pledge.
We will be contacting those with successfully logged referrals after the campaign closes to inform them of their reward and crediting their pledge manager appropriately.
