Public or private: visibility of your posts

How to control the visibility of your posts (blogs, pages, etc.) on the pilot Website? I am attaching a table which clarifies the situation at the moment. Here is a short summary of the most significant points:

• if you don't associate your post with any of the minisites, the entry will be visible to the public unless you mark it as "Internal" under the Access vocabulary;
• if you associate your post with a minisite, the entry will not be visible to the public unless you tick the Public box under Groups (in this case it does not matter whether you mark your entry as Internal or not);

Thus, if you enter general site posts (not associated with your minisite), use the "Internal" designation to control their public visibility. If you associate your posts with a minisite, use the Public checkbox to control their visibility.
