Our Recruit a Friend referral system allows you to send friends and family members Starter Edition activation keys for World of Warcraft via email. With these keys, those you refer will be able to set up their own Starter Edition accounts completely free of charge. Starter Edition accounts created through your referral will become linked with your account. This link will open up a number of benefits for characters on both the veteran and recruit account, including increased experience, character summoning, and level granting!
