Updating Profile in minecraftworldmap.com

I'm Still thinking What is "AID scree name", And any other id tags mean.
I mean like we Fill our Email information with our email

EX:

Email:
[email removed]
But how to fill this:

AIM Screen Name: ??? (where i can get it)

Please if there is someone out there who know what it mean
please replay me as fast as you can.

You do not have to completely fill out your entire profile.
ICQ Number:
AIM Screen Name:
and MSN ID:
AIM is AOL's highly outdated Instant Messaging Service, I do not know anyone who still uses it.
MSN is just your Xbox live profile username.
ICQ is just another semi-outdated Instant Messenger. Again, I know no one who still uses it.

Thanks For the suport Dude..... That's all i need
Onece again thanks.....
