Gmail chat integration has been implemented long before however users were only able to chat with other Gmail users. Gmail has now officially added AIM integration and now you are able to log in to your AIM account within the Gmail chat client. You can check out the feature by clicking on the option menu below the chat drop down menu. After you logged in, you will see the AIM logo beside the screen names. Isn’t it great to be able to chat and email at the same time? The new AIM integration is compatible with IE 7 and Firefox 2. Try out the feature now, happy chatting!
