Netflix ratings (Score 1)

My ex-girlfriend and I... lived together for about four years and had a Netflix account. When we separated, I continued to use it and it's become mine basically. However, together... we rated so many movies on Netflix. Now, if she were to start a new Netflix account, she'd have to restart this process. I could see this happening on many sites where preferences and your history are tracked. I wonder if sites should allow you to clone/fork this sort of thing... or maybe sites should be providing a way for users to group their preferences and ungroup when necessary. After the Netflix, I'm keeping all my stuff separate because nothing lasts forever. ;-)
