This is a list of podcasts available at this site. Podcasts are audio files you can download to your iPod (or other MP3 player if you aren't lucky enough to have the real thing). You can keep up to date with what podcasts are available by using the RSS feed. Preferably use a podcast management program like PlayPod to do this.
My podcast RSS feed is: http://www.ojb.co.nz/owen/XuRSS/RSS2.xml.
