We are not sure how many threads may have been lost but definitely several did go the way of the dinosaur. Unfortunately there isnt anything that we can do when the board suffers a malfunction and threads get lost. We do advise people to keep a text file of the links they post so they can quickly recreate their thread if anything happens to it. But beyond that we cannot, unfortunately, recover those threads that from time to time disappear off the forum due to a PHP/SQL malfunction.
