So i have it on the "show names" view. ...... and it shows my real name and i want it to show my screen name. I looked under preferences and i didnt see an option.
if you have yourself as Your Name and have set your AIM account to be yourmaccomaccount@mac.com, or youraimaccount, and then use that in iChat, you will see Your Name. Like you see Your Friend when you have yourfriendsmaccomaccount@mac.com and he logs in that one.
No one else will see your name. So everyone else see you as yourichatattountname@mac.com (or aim ..) .. and they don't see your name, unless they have saved you to THEIR addressbook. No worries.
