Registered Screen Name Listing

Hello.

My name is Joseph, and I am an AIM user. I was wondering, now. . . If you’ve forgotten some of your screen names, and the like, is there some way to list all the screen names registered to a certain e-mail address, and the like? I know I have some screen names on a couple of e-mail addresses I no longer use, and/or they’re inactive, so I want to recycle these names. Unfortunately, I can’t remember these names, either. So. . .yeah.
Also, do you know of a way to see who registered a certain AIM name? For a long time, I’ve wanted a certain AIM name, but it’s long since been registered, either by someone on AOL, AIM, or Netscape. . . I want to get into contact with this person and see if they’d want to give me said screen name, because I know a lot of people seem to just register names, and not use them. I’ve never seen this person on, either, but they may just be using “privacy mode,” so. . .yeah.

Thanks in advance.
