I have no clue when this happened, but I just got a little note in the Google Talk part of my Google Apps Mail page, saying to sign in to AIM. I did, seems to work great.
The single best feature is that now your AIM chats are logged in your mail, just like GTalk chats. Now you can google-search your AIM chats, which to me, is invaluable.
All I had to do was click the “Options” menu at the bottom of the Gtalk pod, and click “Sign in to AIM”
Hope this helped some people. I didn’t see this posted by anyone else yet, so either I’m last to the party, or I actually contributed something useful for once 🙂
