I think we should either consider audio or video because not everyone has a high speed broadband connection. What my plan is that each one who is teaching some topic can create a video on the topic. He can use any screen capturing tool with audio and share that vedio with all of us. Then I will create a yahoo chat room for this meeting so that people can come to that room after watching videos and can ask questions about it. What say ppl??
PS: I don't know if yahoo is still allowing private rooms !
