Having spent some time developing the code for testing servers to see whether they support Wordpress podcasting, I've decided to pass on the script in the hope that it helps some other confused folk out there. You can download it here.
A bunch of mind-numbing tests will now follow, as we try and work out which culprit is breaking the RSS podcast feed.
Sorry - the site upgrade was going so well, but now I've discovered that my RSS feed links are broken.
The site is being updated - sorry if there are any glitches.
