teaching online with moodle

My students create podcasts (1minute) and I want them to be able to listen to their peers projects. I would like them to be able to upload their mp3 files to a block or whatever and allow others to listen to them.

At this point I have to post them on a server for the students to go to the server link to listen to them. My understanding is that they would have to download the file in order to listen to the audio file. These podcasts have still images, not motion video. Does anyone know an easier way to do this?

Thanks Kate,
This might be something to try over the summer! How do you see them in Moodle? block, web page, rss feed? or another method?
