We've just changed our forum software from vBulletin to PHPbb. We switched forum software because it will allow us to fully integrate the new design we are working with on with the forums for complete site-wide integration. In the long run, the change is for the best.
The forums are back online now - all posts are still in place and you do NOT have to register again. Please stick with us while we modify the forums and add new features. This will take 3 or 4 days (maybe a tad longer) to complete properly.
