iTunes got it's knickers in a twist this morning and hung. I had to end the program to get it to close. (In hindsight, a bad move). Anyhow it's done now.
Consequently when I open iTunes, all my subscribed links have gone so the podcast view is completely blank.
Do any of you clever folks know (apart from making a note of all links I subscribe to) how to make a backup so if I ever loose them again, it's a simple case of restoring not having to add the links one by one again.
