Sims 3 Online Feature

I wanted to ask something about it, as you know from previous talking I
have some original sims... But i have put them on the sims.com site for
my account... But I have also install the game to my aunt's computer to
play and want to play online with me... How i can make her go online w-o
have an extra original cd key? Since is not let me put my own keys in
the registration?

Thank you in advance, is really important to us xD

Are you talking about registering your account on the website? Only one account can be registered with a serial number.

Hello,

... and original, legal code, to be precisely.
