There was an expansion of the podcasting offerings on mnartists.org recently. For an example, go look at the Radio mnartists page. The podcast is the same link as the RSS (the graphic on the right of the header, near the center of the page). Copy the link off that page, or just use the direct link below, and subscribe to the feed in your favorite podcast player.
Direct link to the podcast:
Radio mnartists: http://mnartists.org/resourceList.do?action=rss&rid=82170&pid=219
Subscribing to a podcast with iTunes
Copy the direct link. Open up iTunes. Pull down the “Advanced” menu and go down to “Subscribe to Podcast…” then a window pops up and you paste the url into it and hit return. Then iTunes will automatially check mnartist.org for updates to that set and download them for you.
