Reference page for AIM/ICQ of friends
Short, concise description of the idea
Make a page that, when accessed by a logged-in user, will display the AIM screen names or ICQ addresses for all the user's friends who have that defined.
Full description of the idea
This would work something like birthdays.bml. It would list all your friends who have a screen name in one place. This could be one page for all the messenger services, or a separate page for each one (which would probably be easier to lay out.) Only you would have access to your list.
