OK i have TBC up on my main account that I have had for years. With the new 'invite a friend' going live i have finally decided to take the plunge. One question that still gets to me that i cant seem to find a direct answer to is the following

1) Main account has TBC

2) 2-4 (slaves) will be "invite a friend" and thus will be trial accounts.

The question is for accounts 2-4 I will have to upgrade them to Normal then TBC. In singapore its like $65 each for the disks for Normals + TBC. I will have to spend 130 x 4 in order to get 4 accounts up to spec as my main?

2nd question. Assuming that all accouts are at TBC level (ie i can lev to 70 on them) Do i have to have 5 seperate installs of wow on my pc or can i run 5 of them from 1 install using keyclone?
