removing podcasts?

This was probably a blunder on my part but... I deleted my web site before I removed my podcasts from the iTunes directory. Look up "today's insight" by Rick Allen and you will be unable to download the podcasts.

I am in the process of creating more episodes of "today's insight"s but for whatever reason the iTunes Directory doesn't want to accept the feed.

How do I get the first podcasts directory information removed? thanks
