having user site as a menu page

Hi,

My site currently have a "blog directory" that link all user sites into one of my menu tab called "salong listing" . I would like to create a privacy site for all my user admin to get access only. And this privacy site is just like another regular site that have several menu tab. I there a way, that I could link this privacy site directly into one of my menu tab on my main page? For example, one of my tab menu in my main page called " Salon Owner", how can I link one of my privacy site into this "Salon Owner " menu tab for only salon (site admin) to view?

Thank you very much.
