The style guide has been done for quite a while. Too bad it's just no where to be found on. Only about 15% of it has been published now.
The design team simply just needs some additional hands. After a lot of intense work leading up to the launch of the new CI we've been having difficulties finding the time to get some of the last parts done.
If you're interested in just helping out publishing the SG (10 man-hours would get us very far) - or perhabs interested in getting some experience in hands-on identity design work - then please just drop me a note!
The CI project will actually never finish so there's lots of room to really contribute and do more actual designing here.
I'd really like to advance this project further. And we have tons and tons of great ideas about what to do to push out more design for everyone in the community and beyond to use - templates, downloadable versions of everything, FAQ's, updates on the default skin etc. We just need more hands to help out.
