Who the *** are the jonus brothers? And A Zacky V Question

Okay so hi!
Who the fuck are they? Have i been like living under a rock or are they just some new teenie obsession?
Also ... I'm thinking about making a zacky V Fansite... to spread the word on his awesomeness!
I'm currently trailing to be an web designer so.... yeah and i was wondering if there is like anyone out there that would be interested in helping me out? You dont have to be fully experience or anything... just know some basic crap... maybe some flash and photoshop or fireworks. and a bit of basic HTML or know dreamweaver or simular....
