This website had some security vulnerabilities that had to be patched. I recently completed an upgrade of the site that should be transparent to the normal user, but if you are adding content or writing posts for the site then you will instantly notice the changes. In the admin areas the design has changed significantly. It should be intuitive, but if you get lost leave a comment here and I will answer any question you have.
Note to self: update the screencasts with the new admin screens.
