The site is back up and operational, and upgraded to the latest version of Xenforo software. For those that were unaware (or even care), the Xenforo company finally got out of litigation (being sued by vBulletin). And they are now free to upgrade the software again. It has been roughly 8 months since any upgrades rolled out. Should expect a new version with more features to show up shortly, with an upgrade to v1.2. Here is their forum where they showcase some of the new features in work:
