Thanks! Actually if you want to work on the API reference page, that should probably be it. As for the "user contributed notes", can you further explain your idea?
As for working on the API reference page, I wish I could. Hopefully I have enough knowledge to share after I learned more and I will certainly try to help when I'm at that point.
'User contributed notes' are user comments underneath each section.
Basically, where users can submit section related remarks, pitfalls, example code snippets etc. (that maybe can be voted up, down or away).
