Just so as long as your friend starts a brand new World of Warcraft account (this can be done on his current Battle.net account if he would like) then you two should be able to take full advantage of the Recruit-a-Friend program. If you are planning on inviting him, though, make sure that the account that sent the invitation logs out before the other player accepts it-lest you end up creating the World of Warcraft account on the veteran account holder’s Battle.net account.
