CMS Press opens up the ability to create and manage custom content types and taxonomies for your WordPress site. 
It adds the flexibility to have more than just posts and pages for content by allowing the user to register their 
own post_types that can use their separate theming from the post and page template along with its own permalink structure.
Along with custom post_types, CMS Press gives users the ability to register their own taxonomies. With the addition of 
custom taxonomies, a user can tag or categorize content separate from the default tags and categories.
