Hi Stacy,
Unfortunately I don't have students do podcasts on a regular basis; I use snapkast although I am attempting to work out the record function on my smartboard so that we can do more podcasts. Here is one website I have looked at http://web.mac.com/mrstanaka/How_To_Podcast/How_to_Make_a_Podcast.html
and another website

My vodcasts are at http://devos-podcasts.blogspot.com but my students' aren't there they only reside on our school network.
I hope these help you!
I don't do podcasts on a regular basis, but each grade level 3-8th will have done one by the end of this year. We did a full class podcast in 3rd, are working on individual ones in 4th, partner podcasts in 5th, partners in 6th, individuals in 7th and will do individuals in 8th.
You can go here to see them. At this point, they are all in the archive grade level pages. The links are at the bottom of this page. I uploaded all their podcasts to my wiki, so they are all the audio files.
The only podcasts we've done was part of our Titanic in the Classroom Unit. Each student chose a passenger or crew member and wrote a biographical sketch--then podcast. You can hear them here.
