Creating AIM / ICQ Accounts
The base requirement for this is that you have an active account here at MacDomain.

From your dashboard, you have a link to create both an AIM screen name as well as an ICQ account.
Once this is done, the creation links will vanish.

Extras
Since the creation links will vanish, what replaces them is the possibility to change your AIM and ICQ account passwords, should you ever forget them.

You will also be able to see your screen name and UIN, should you have either or both account types.
