If your friend is listed as "Pending" or "Approved" in your Referral overview, everything will be fine automatically! The system will automatically process your referral bonus within about 3 days.
If your friend is not in your overview, they have not been able to enter your referral code correctly. They can still add it within 7 days after creating their account !
If your friend could not enter the code in time, unfortunately you will not receive a referral bonus this time!
