If you have iTunes, it is really easy to subscribe! Just click on Podcasts -> Podcast Directory, and type Pole Vault in the search feature, then click subscribe.
If your version of iTunes doesn't have anything about Podcasts, go to http://www.apple.com/ and download the latest version. I know version 5.0 just came out for the Mac. I don't think I like the new burnt aqua interface, but whatever.
