When setting up your multiboxing team, what is the easiest way to set up new accounts? I'll need a new registration key for each account and I'll also need to enable TBC for each account. Is it possible to purchase registration keys online from Blizzard? Is there any way to avoid having to purchase a new box of software from the store for each account?

Secondly, once I have purchased separate accounts, how easy is it to transfer characters from one account to another? I have heard that it is possible to transfer characters between accounts but that there are rules in place to safeguard against people using this to sell characters to others. Does anyone have any experience doing this? Do I simply need to be able to prove that the characters are being transfered between accounts all owned by the same person?

I'd like to add that I am very fond of dual-boxing.com! Since discovering it some time ago it really has helped to open up a brand new way to enjoy the game. Great work!
