General Support: Re: Cloning the whole page in the private area
Note that there's no automatic way to clone lots of pages from one site to another, or from your live site to the private pages.
Though, that said, yes there's no reason why you shouldn't use the private area for this purpose - you could experiment with various features that only your chosen users could see, and then replicate these things onto your live site as and when you're happy with them.
If it's just one or two pages, you could manage this in the CMS by creating a test page and giving read access only to those users you wanted to be able to see it, then you could give the page public read access once you're happy with it.
