Well, to start it off mac.com screen names cannot be banned with the "chat owner" option. they can also not be actioned by aol, or suspended. Contrary to popular belief, they do not expire (at least while only being used for aim). they can however be gagged. you can also put in any string like 'aol' and 'host', if you put 'host' as a prefix for your screen name, you can enter full chat rooms.
And example would be this: I register the mac member name bigblueball and i can sign on aim by typing in
bigblueball@mac.com and it will work, and my screename will be a link to send a email. If i register
hostbigblueball@aim.com i can type in this for my AIM sign on:
"HOST
bigblueball@mac.com" and it will look like this:
