I am not up on all the terms yet I think boosting is towing a lowe level with a high level??

One trick is to go ahead and do that. BUT before you turn ANY quest in, drop the high level char and summon a same or lower level toon from the linked account to the one turning in quest. I tried it once In tanaris and even a lvl 1 worked! Then when they are together and partied turn in the quests. you should see the 3x xp bonus for the quest, then you can drop the little one and bring the main back on to continue..

You lose the kill XP bonus, but the quest XP is really where the RAF program shines. From what I have seen with same level linked group the per kill xp is a little under solo rested XP.
