I don't know who your last webmaster was, but he sure sucked! 
Anyways - I don't see the a link anywhere telling how to subscribe to the feed. I assume that this is already on your website 'to do' list...but...I figured I'd post something just in case. Without that info, new listeners (or unsubscribers) will have to download each show individually.
Here's the URL to put in the podcatcher: www.skydiveradio.com/skydiveradio_rss.xml
