Since the TCR reboot, I have been dumping every episode into the archive.org listing for the show. This listing has every surviving episode of TCR, but this past couple weeks uploads have been failing and finally I can't seem to make it work.
All old episodes still survive, but it's not accepting new ones. I'm working to resolve this. I'll make a post about it as soon as it's working. In the mean time, Podomatic is still in business. MP3s can be downloaded from the Podomatic page, and there is now a TCR playlist in YouTube.
UPDATE: This now appears to be resolved. Thanks!
