The Content Management System restricts access to registered users. Attempting to access a CMS page without having properly logged in will automatically redirect the user to a sign-in page. Content items are created either by entering text in a browser or uploading files. In addition, an authorized user can add/edit extended attributes associated with the content item. Content items may also be edited by entering new text via a browser or uploading new files. Changes made to the content or extended attributes are stored as revisions of the content item. &managing-templates; Content may be previewed at any time (even before deployment) so long as one revision is designated the Live Revision, the revision that will be previewed. Content can either be deployed immediately or scheduled for future deployment (and expiration). Before deployment, however, the content item must satisfy the following preconditions: One revision must be designated the Live Revision, the revision that will eventually be deployed. The content item must be in a publishable state. The exact conditions for a content item being publishable will vary from item to item, depending on whether that item requires components to be finished and whether that item has to pass through the production workflow. &page;
