If you mean connected to Nickelodeon, then no. If it was, the layout would be more professional looking/would most likely use Flash, and there would be Viacom copyrights at the bottom of the page instead of free server/website hosting links. Links/promos going back to Nick.com would be probable as well.
I think the person who started the site posted on the MMO-Champion forum asking for help with it, though.
Ah, that I can't answer until there's more reviews around. It does seem to be fan-made, though, and unless they ask for private information or money in order to play, it should be okay? Although it doesn't hurt to have browser security features like NoScript or RequestPolicy, just in case. *shrugs*
