We have enabled the new site theme for testing on your site.
How do I enable it?
What type of feedback do we need?
Bugs related to your sites theme: Please help us look for issues/bugs related to the theme design and how we have mapped the old theme to the new. This needs to be done within the limits of the new unified theme. I will post on each site when the theme is ready for testing and bugs should be posted as answers to that post with the details (including images please!).
General concerns about left nav or theming: If you have concerns or issues regarding the left nav or the overall approach we are taking to theming, then this Meta Stack Exchange post is the right place for feedback.
What new theme?
If you're like, "What the heck are you talking about?", then you should read the Meta Stack Exchange post entitled Rollout of new network site themes (and maybe the posts it links to for the full background).
