Question about new RAF feature and new 5 box crew

Hi,
i have read a lot of stuff about the new RAF but some things are not clear to me (maybe because english is not my native language). I already have a group of 5 shamans at 70.
My goal is to level a group of 5 characters using the triple xp. How do I acomplish that?

* From what i understand I can create 5 accounts (first one inviting the second, 2nd one inviting the 3rd and so on). When I level chars on those 5 accounts together they will all get triple xp (provided they are on the same level). Does this work? (And although not important to me: will this get me the zebras on accounts 1-4?)

* If that doesn't work: Can I somehow use the 5 lvl70 shamy accounts i already have to create a new group with triple xp?

I have already started playing a new group before the raf feature (currently level 27). Can I get 5 accounts (each being invited by one of the lvl70 accounts I already have) and transfer my lvl 27s to those new accounts? Will they get the triple xp?

Sry if some of that information was already provided by other threads; maybe someone could write a small "How-to level 5 chars using triple xp"?

Thx for the feedback,
Bunny
