your plugin is working well.
I need to access to rss feed of placemarks via the custom post type. But unfortunatly I can't.
I imagine I should have a result if I type http://www.mysite.com/placemarks but I have a 404.
If I type http://www.mysite.com/placemarks/my-placemark it's working for this placemark.
As I need the list of all placemarks, is it possible to call it via the custom post types ?
