So it was pointed out to me today that it wasn't possible to actually download any of the mp3's of the podcasts I've been posting to this site. I was confused by this, because any time I'd look at a page where a podcast was posted I'd see a download link under the player.
It was a permissions problem. I didn't realize it was a permissions problem because I have an admin account, and of course administrators can see everything. The permissions are now set correctly, so y'all should be able to download any and all podcasts posted on this site.
Sorry about that! Fixed now.
