I work at Calvary Chapel Chico, and recently the head Pastor here (Sam Allen) asked if I could start a Podcast for his daily radio show. I said "Sure", wow, that was premature. It took me a month of trying on my own, and then I found Pod-Serve.com. It works perfectly, and its still in alpha. It will automaticly list you on iTunes and Odeo (and itself). I'd recomend it to anyone.
