Public vs. Private iTunes U Site

Question

Can someone please correct or confirm my interpretations?
1. The iTunes U Private and Public sites are totally un-linked as far as content?  The content copy was one time, all other files will have to be uploaded to each location separately?
2. The access role All@urn:mace:itunesu.com... is now non-functional in iTunes U private site?
3. iTunes U private site will no longer generate RSS feeds of content?
Thanks for any insight you can add.

The below in BOLD is what I am trying to do, but do not have an option to do.  Is this something Apple must give me a role or permission to do?  I am already and Administrator..  Thanks in advance!
To add content to your site you must create collections containing the course content, series information, or items you want to share with your users.
To add a collection:
Click Collections at the top of iTunes U Public Site Manager.
Click the Add button.
Choose one of the following from the pop-up menu:iTunes U Public Site Manager adds the new collection to the collections manager page.
Provider-Hosted Feed. Choose Provider-Hosted Feed to add a new collection from a feed URL hosted on your servers, type the feed URL, and then click Add. For example, http://www.example.com/rss/provider-hosted-collection.rss.
Apple-Hosted Feed. Choose Apple-Hosted Feed, if available, to add and edit a new collection from a new RSS feed hosted on Apple's servers, click Add, and then use the feed editor to add channel and item details and upload content.
Copy from Original iTunes U Site. Choose “Copy from Original iTunes U Site” to add a new collection by copying a group from your original iTunes U site, type the group URL, and then click Add. To copy a group from your original iTunes U site, navigate to the group, Control-click the group's tab, choose Copy Link, and then paste the link in the Group URL field.You must be an administrator to use "Copy from Original iTunes U Site".

If you add, remove, or hide a collection or update an iTunes U Public Site Manager page, you must publish your site for the changes to appear in iTunes U in the iTunes Store. Publishing changes can take up to 24 hours to appear in the iTunes Store.
