Because I'm an idiot, a post that refused to cooperate with the UTF-8 updates recently got axed in order to stop the site from throwing back errors to Google, Yahoo, etc, as their bots were scouring the archives for stuff. You can read more about the UTF-8 junk in the other thread.
In the meantime, content restoration for the "Password Corruption" bug discussion. http://www.smaugmuds.org/index.php?a=page&p=16
For whatever really strange reason, it accepted the text via the custom pages module. It's imperfect, but does the job. If the participants in the thread want to try and piece together who said what, I've no objection to trying to repost the thread manually to see if just reentering the data through the forum interface works.
