In case anyone's blocked from the wow forums at work:
Greetings, all!

Several players taking advantage of the Recruit-a-Friend Promotion have brought it to our attention that they are unable to grant levels earned prior to patch 3.0.2. We have made our Quality Assurance team aware of this issue and they are working to resolve this issue as quickly as possible. Unfortunately, we do not yet have an ETA to provide at this time.

Please keep all discussion related to this issue isolated to this thread. All additional threads will be locked and/or deleted. We will do our best to update you as more information becomes available.

Thank you all for your ongoing patience and cooperation.
Q u o t e:
Are we going to lose the ability to grant levels if my friend and I level past 60? We just came to a new server recently and dont want to wait till 3 mins before WOTLK comes out to level to 70...
Leveling past 60 will not affect your ability to grant levels. Please refrain from transferring your character, however.
