Blogger.com, the host of this site, has introduced a new beta version. Foolishly, I signed up for it immediately. Unfortunately, my podcast host will not allow me to post episodes of Matt's Today in History here. Hopefully, the issue will be resolved soon. Thank you for your patience and understanding.
In the meantime, please consider downloading and installing a "podcatcher", an application which allows users to subscribe to podcasts. I use Apple's iTunes. It is free and, in my opinion, easy to use.
