I regret to say that we have had a catastrophic hardware failure with our forum server. We rebuilt it and attempted to revert to a backup of the forum a little earlier in the day.
So far we have recovered data until August 20th and are still working to recover more. We greatly apologize for any confusion caused by lost posts, topics, and user registrations.
We are sorry for the inconvenience.
