How do I replace an episode?

To replace an episode, you can simply go to your Dropbox. First, delete the old episode, then you can put the new audio file inside the Dropbox folder. Then rename the episode to the original name. Another way is to make your new audio the same name, and then overwrite with your original audio file by drag and drop the new one over. Either way, JustCast will detect the changes and replace the episode.
