A you can see Leon went though and enabled the special 'wiki features'.
I disabled one of the (comments) since it made talk pages inaccessible, but I left the others on.
The new navigation bar, chat and badges are all available for contributors.
That being said, they can be turned off at any stage.
If anyone likes/doesn't like these features, post feedback here and we can enable/revert them.

Well, the features are a bit odd, but I've gotten used to them, so I'm good with them.
