Check authorized macines in Itunes

[colecifer]

I just got an ipod for christmas and at the same time started using itunes. I just set up an account to try out the store and it worked fairly well. One thing i'm confused about is under acccont info it says two computers are authorized to play files on this account. I only have itunes set up on one computer, where is the other coming from? Its not a big deal, because i sort of found a work around to the rights management(i won't say how because i think i might violate pc mech rules) but i am still wondering what else is authorized.
