Found an error where you could keep adding the same thread to the archive. It just made duplicate entries in the table, but it still meant checking the archived threads extra times and having more than one entry is obviously pointless anyway. FIXXED.
Also, http://chat.thisisnotatrueending.com is a redirect to that shitty Angelfire site where I've got the Meebo chat embedded. If the site's down for whatever reason (like today when I broke the site with an errant semicolon and then the server crashed later on) you can still get to it easily.
