I spent some time implementing my theme idea to the lostwages devel version of the WineHQ website.
Take a look at: http://lostwages.winehq.org
On the home page, use one of the three theme links. I've made the skinning engine pretty simple so more themes/skins could be added in the future.
I also removed the hidden menus, and returned to the standard view like Francois has been evangelizing. Most of the links go 404 for the moment. But the About page is in as a sample.
Next on my list is to work on using /about/ style URLs instead of page=About get style.
Then I need to port WWN to use the new theme engine (its busticated in the lostwages version).
That's all for now.
