Creating a 2nd account question..

[LImitPlayer]

My fiance wants to give poker a try.
I was going to create a 2nd account for her on pokernow but it won't let me. I tried the other party skins but we have the same problems. It wont let us create a 2nd account an any of them.
I have all the party skins on my computer and have an account on all the them.
I was under the impression that some people have more than 1 account per household, if so how do you set this up?

Or do you share an account with you husband, wife son, daughter etc?
