Philosophy Forums was hacked on September 6th. Due to the hacker, everything between July 24th and September 6th is permanently missing. Unfortunately, automated backups had to be turned off months ago because they were crashing the server. We're evaluating how to stop this from happening again. You may be able to find your own posts in a google cache to re-post them, if you want to.
