Plugging my new plugin http://wordpress.org/extend/plugins/podcast-channels/
* setup multiple podcasts in a WP blog
* replaces the functionality in PodPress called 'category casting'
* adds duration and 'explicit' flag to audio items in the Media Library
that's (mostly) it. no inline player functionality - other plugins will do that for you.
i'd love some feedback. the admin interface is jquery/js heavy, so any browser problems with it - let me know.
