If you choose to delete your feed from FeedBurner, you can redirect all subscribers back to your source feed for 30 days. That should update everyone automatically, saving your subscribers a little bit of work. If there’s ever anything we should do for our service that you felt was missing, please let us know!Regards,Regegevian Rick, Executive VP of Business Development at Feedburner,receiveanonymouslyresponsibilityforsubscribers.”]
