If you are wondering where some of the previous episodes have gone to, then sit tight. I am in the process of getting everything back to normal after upgrading the PodPress plugin to the site. I hope to get all the older episodes added back in over the next few days.
My apologies, and please check back soon.
Edit: (7:52AM PT, April 5, 2006) I made an error in the upgrade process with the RSS through PodPress, causing my feed to not work or be seen. This situation should be resolved. If you are still having problems, please let me know.
