Where would it be preloaded from? You can use ?action=edit&preload=pagename on any url to editing a non-existent page, so you could use parser functions to determine which page to load. Also, CreateBox is useful for page creation and is enabled by default. Although, this is assuming that you already knew about preload=, so that alone may answer your question. It loads the content of the specified page on the page you're editing.
