Make sure you have iTunes v4.9 which supports podcasts.
Until we are listed in the iTunes directory, we can not use the one-click subscription, but you can still add roocast to your iTunes software. Just use the Advanced dropdown menu and "Subscribe to Podcast..." Past in our URL: http://www.roocast.com/feeds/roocast.xml
We will provide the one-click subscription as soon as it is available.
[UPDATE: roocast is now available in iTunes as one-click. See the link below for the latest.]
Until we make it into their Top 10, you will need to search for "roocast" podcast. Then, just add iTunes to your subscription. Easy peasy.
