Everyone,
These changes have taken a long time, I apologize. With that, I have great news! Today I have completed new Category Podcasting options that solve the problems discussed in this thread.
Two new options:
Strict Category Podcasting
You can now specify which category your episode should be associated with in the episode entry box. This allows you to select as many categories as you need, only the episode selected category will be used for podcast measurement and subscription tools.
Podcast Only Category Feeds
A podcast only feed is provided in addition to the regular category feed. This allows you to mix blog posts in your category while providing a podcast only feed that only includes the episodes (optimal for iTunes).
Please contact me at cio [at] blubrry dot com if you would like a preview of this release.
