PODCAST...

To whom it may concern;
If you have any understanding of how I can set up a podcast and connect it to my blog please let me know. I think I have a faint idea but could use some help. For those of you who think I'm speaking another language... a podcast is an audio file that can play on MP3 Players such as IPODS and through the speakers of your computer....which means I could record messages and save them to my blog...Which would be way cool and a ton faster then typing...
Any help would be greatly appreciated.
