If you have directly bookmarked any story or discussion (such as the Robin Hood's Grave stuff), you've probably already noticed the link is broken. When we migrated the site, all the entries got assigned different numbers. To find your favorite discussion, you'll need to first visit the CATEGORY archive (science, etc.), then search or browse to your favorite entry.
Google searching won't work, at least for awhile, because it's keyed to the old site.
