Triple experience requisites:
Rule 1) Veteran and recruit character must partied and within 100 yards of one another
Rule 2) Mobs killed and quests completed must be marked neither "Low Level" nor gray in difficulty for either the veteran or the recruit character
Rule 3) Should one character be more than 4 levels higher than the other, only the lower level character will receive the experience boost. Rule 2 still applies.

http://us.blizzard.com/support/article.xml?articleId=20588 The inherent rule not mentioned is that accounts must be linked in order to qualify, and, in order to create an account link, an existing WoW account owner needs to refer a friend or family member by issuing an invitation. When this invitation is used to create a new account, a 90 day link forms and grants specific benefits to characters on the veteran (recruiter) and recruit account. Invitations may not be issued to preexisting accounts.
That should cover you! If you've any further questions, though, Beastios, please let me know. :)
