Does anybody know how to change the title of your podcast on iTunes and the description of it?

You change the title and descriptions by entering the changed versions in wherever you originally entered the items in whatever system you are using to create your feed, then re-publish the feed; it will take the iTunes Store a couple of days or so to catch up.

However, if the method you are using to create your feed is one of those which uses the title of the podcast as part of the URL, and this changes if you change the title, then if you change the URL as a result the iTunes Store will lose contact with it and fail to update in future: so be careful about this.

You don't want to change the feed URL whatever you do, that't the vital point. What actually is the URL of your feed? (Please always post this when you have a question.)

The title of your podcast is Jose Tboada, both in the feed and in the Store, so the feed has not changed. However it looks as if the URL of the feed is fixed, so that shouldn't be a problem. You now have to find out how to change the title given in the feed, either in Wordpress or Feedburner.

The title of the feed is still Jose Taboada so evidently there is somewhere in Wordpress you need to change it, and make sure you upload the revised feed to the server. The title of the webpage linked to in the feed is 'After the Count' so obviously just changing that wasn't sufficient.
