At the moment, a friend and I are enjoying the ability to make podcasts for free with Garageband, using iChat to get both of us on audio together. I use a mac, she uses a PC, and we can do it with iChat and AIM. However, we want to turn our podcast into online radio, and were wondering what program I can use to do that? I tried one which was a trial or something that was 40 dollars, but it didn't even work... if anyone can help it would be great.
