I got a welcome podcast up on Classblogmeister. It may have taken more steps than necessary and I want to have an enhanced podcast eventually with multiple images, but I have a welcome podcast!
I used a podcast creation guide from Apple that I found on Google. I found background music at podsafeaudio.com. Mixed it up in GarageBand. Exported it to iTunes. Uploaded it to a podomatic account. Finally, added my citation for the music and downloaded it to my iPod.
This makes up for the Internet being down in the school. I'm still crossing my fingers that it's up on Tuesday after the workers in the building finish their work.
