I found this simple podcast authoring tutorial, I think it is very useful and have some good tips not only for the recording bit, but also for the content itself. (for PC users, or for more info there are other good and easy tutorials online)
I have also updated our HowTo page to refer to the new podcast features. This is relevant to both audio and video.
If any of you are having any questions about this, please comment here (so I can answer publicly too)
Enjoy.
