How do I make a podcast?

[gazfocus]

I have been asked by my church to publish our sermons on iTunes as podcasts. How do I do this?

I have the sermons in MP3 format. We want the podcasts to work in such a way that someone can subscribe to them, etc as normal.

Thanks

Podcasting for Dummies. I'm not joking, I have it myself. There's also this for free, online help.

Just Google "podcasting tutorial" or similar search terms.
