Notes and change of Screen Name

I only learned today, that on party, and probably on all sites, that if you have notes on a person and they change their screen name, that you no longer have notes on that person and basically lost all the notes you had on that person.

What a weakness to the note taking system. but then i guess if they allowed one to see notes if a person changes screen name, the change of screen name would lose its meaning. what a dilema this is.

But i really would prefer not to lose notes on a person. A big problem, I find. I wish there was a solution.
