Wild Things: YA Grown-Up discussion

So I recently discovered this series through a site I visit... It looks kind of cool but I checked out the website and got really confused, even after I read a couple of articles. Does anyone know anything about this or how it works?

I am just trying to figure out how the users online figure out what to say, if it's all just made up by them or what.

That blows my mind! Haha. These kids and their new-fangled way of doing things.
