Can burning crusade be used for multiple accts?

[dcb91]

i'm sure your all sick of hearing about the burning crusade, but one quick question... if i buy the expansion, am i able to install it on my pc and lend it to my friends so we can all play it online together, or is there a CD Key or something like that? thanks.

I dont play...
But id imagine that it'd be a key code type thing...
Cause then what would the point of selling 2.4million copies in 24 hours.


Though it is an expansion pack....



But I am leaning more toward the key code theory.
