Can't find old forum post with Search

I did a search for “manila” hoping to find a good way to store manila folders per David Allen’s suggestion to avoid hanging file folders. One of the links (the third one, to be precise, was this: http://board.43folders.com/archive/index.php/t-1146.html. But when I click on it, I just get redirected to the main forum page at http://www.43folders.com/forum, no specific topic is listed. What’s up?
