No, he doesn't have AIM. One good option for us would be the program Skype. It's free and we could set up group chat rooms as well as group voice chat rooms where all of us would be able to speak to each other in a virtual "classroom". It works with Hebrew so we could work on our spelling and writing and vocab in the typing chat rooms, and our pronunciation and speaking in the voice chat room. I also believe that there is a way to do a combination of both voice and text.
