New to multi-box

[SuperMiguel]

So i want to start multiboxing, started today, got everything installed, Using an older system (part for a new system should come in tomorrow) now im running 2 toons a mage and a priest, i eventually want to run 5, but i think it will take time for me to get used to it...

So i currently have 2 accounts 1 with 5 lvl 80+, 1 90 (priest) and 1 with a single 90 (mage)

No i think having all toons to be the same will make my life way easier at least for starting... So i was thinking to make a DK, since they are the one that start at highest level and i believe that 5 of them in a bg would be cool, but also thought i would need a healer, So not sure if i want to use 4k + druid healer or 5 dks... What you guys think? So i already have a lvl 85 dk, so i need 3/4 more, i guess i also have to transfer my toons around to one of those new accounts, so i can create the dk (previous lvl requirement) now how would i go about leveling them fast? how can i use that refer a friend thing to create a account on my same battle net?

How you guys do this?
