I need help figuring out how to use multiple users on iChat. Whenever my girlfriend or a friend of mine wants to use iChat and go on their own screenname they simply add their AIM information into iChat and sign on. However, whenever they IM someone it says my name "Jason Stevens" instead of their screenname. In addition, it changes their icon from whatever they set to the one I use on my iChat account and on my mac. How can I fix it so that they keep their screennames and their original icons? Thanks. P.S.- I don't want to use Adium because I do a lot of file transfers.
