Well really it's just a bad link, but still good for a snicker on a discussion about bugs. This is on the subforum title where it it says:
Lamannia Bug Discussion
Before using this forum, please click here!

The "click here!" link goes to:
http://www.ddo.com/en/showthread.php?t=359593

...which results in a "404 Not Found" error.

My guess is the link was not modified for the new forums.
