I deleted a couple of broken links from our profile (diagnosis) page.
One was for a community on LJ that was deleted years ago. The rest had been separate forums at Knight Rider Online that are no longer there.
Also deleted links I had to both the Knight Registries and the Foundation replica boards. I don't know about the main site itself, but the message board for the Foundation has moved to FB. Pretty sure it's the same deal with the Registries.
ETA - I've also done away with the links to knightrider.nl and knightrider.org in the sidebar. I don't even know if those sites still worked.
