I meant to announce this weeks ago.  Sorry :(.  Anyhow, “Ouran High School Host Club” volume 16 is available now from Viz.  I recommend this translation over anything available in scanlation.  It is superior :).  The book is available now through the special Ouran section I set up in the Omari’s Sister Amazon Store.   Click here to buy and support Ouran, Hatori-sensei, and Omari’s Sister with your purchase :).
