I had earlier written a post on recording skype conversations using Audacity. I just found a video on google video. This is would help you explain the setup in case that was not clear! BTW the video tutorial proves video – image + audio is a better medium for learning unlike text! 
The video says RSS but you will have to find a service to upload the audio and get RSS out …
Vinu,
Thanks for your two videos on podcasting using audacity. I’d like to show them to my students. (I teach 7th grade at a middle school in Wisconsin.) However, I can’t seem to view the files at school. Any chance you could send me the quicktime file directly instead of using the link on the computer? Again, thanks for a great resource. This is a new adventure for all of us here at WHMS and I want to get them started on the right foot.
