Beta 18 is out so this thing is going at a snails page.
I have two test sites going.
First has a static header footer which supports user login and style integration A community photo gallery - My Photo Gallery
Second one below has full header footer integration but if you try viewing a user profile or a photo you can see what is stopping us from supporting full integration the pages are not viewable. A community photo gallery - My Photo Gallery
Basically with the beta going slow that is a good thing. If I can figure out what is stopping the full integration then I can try fixing that otherwise at the bare minimum we can support style and user login.
