Could you be a little more clear? I dont know if I understood what your asking.
I assume that you have been using AJAX and your past the begginner level.
The website you mentioned does have a forum section and is probably a better place to find more advanced info.
Hope that helps.

You can't get to the advanced levels without practice. And when you practice you'll automatically know what to explore. :)
