Phobos documentation improvements

[Mark Isaacson via Digitalmars-d]

I am doing an independent study at university this term to 
improve the general quality of life in our D community/ecosystem. 
I was going to start by improving the layout of the Phobos 
documentation/adding summaries to each module, but noticed that 
someone is already working on that front (indicated by the 
"Preview new Layout" button on the home page: 
http://dlang.org/library/index.html).

Three questions:
1) Who's working on this?
2) What's the best way to give feedback/best place to discuss the 
changes (is there an existing thread, for instance)?
3) What's the best way to contribute on this front without 
stepping on any toes? A link to the appropriate fork of the 
documentation would also be welcome.

Thanks!
