The easiest way to record group podcasts is by using Mrs. D's AWESOME iphone and a really cool app called AudioBoo.
Click on the purple Audioboo icon and the middle record buttom. When you click start, it gives you a 3 - 2 - 1 countdown.
"Record"!
A blue bar will appear at the top. Hit "pause" if you need a break, "resume" when you're good to go.
You can "restart" and "discard".
"Publish" when done. Describe your boo, (e.g. Courier du Bois ts#).
Tag it "ts", "Upload".
After a few hours, it will appear in my Audioboo account. I'll drop it into this website, where you and all your friends can enjoy! (Go to the bottom of favourites line page to see an example).
(see why I love this iphone?!)
