To configure and see the addresses of the feeds of a podcast go to http://www.podigee.com/podcasts (log in if necessary) and click on the name of the podcast you want to configure. Then choose the tab Feeds.
Number of feed items
Here you can change how many episodes appear in the podcast feed. By default the latest 10 episodes are included. You can choose to include up to 100 episodes in the feed.
A word of warning
Do not set the number of episodes too high. If your episode metadata is large (for example if it has a lot of text for show notes) some podcast clients (including iTunes) will not be able to read your feed properly.
To provide a solution for this, Podigee offers paged feeds. This allows podcast clients to find all episodes. This keeps feed sizes low by only showing the latest episodes and adds further information to the feed that allows a podcast client to find all episodes of a podcast.
Unfortunately only a few clients support this. If you would like your favorite podcast client to support it too, please write them a message and point them to this URL: http://podlove.org/paged-feeds/
