May have messed up RAF accounts

[Ouroboro]

Alright so what I planned on doing was getting 5 shamans to multibox with, and I have gotten everything setup and the accounts are running. But I just realized that the accounts have to be invited by a main account to get the RAF and XP bonus so is there anyway to link accounts even though they have already been created normally? Or am I screwed leveling without the XP bonus and the free levels?
ATM none of the accounts have RAF because I'm a dumbass and made them without an invite.
