I was messing around on the Hana To Yume site, until I found this web page:
I can't read Japanese, but basing on the appearance, it is most likely a timeline of the mangas that the magazine published. At the 00's, scroll down a bit, and you could see the Ouran's first volume just above Skip Beat! and Fruits Basket. Also, if you click on the Ouran's first volume, you could read the first chapter, but it is in Japanese. Plus, if you scroll down even more, a lovely image of the host will pop up.
Just sharing this information, this is also a proof that Ouran is still remembered by many even though it has ended years ago :)
Spoiler! Contains the pop-out image from the website!
Also, here is the anime's website in Japanese:
^ I love this website, it contains short summary on the anime episodes, Ouran goodies, a brief summary about the characters and more..
