The Panopticon/Monobook header needs a link updating

On Monobook, the following message is seen at the top of the page:

Most visitors to Tardis do not use this skin.

Our primary stylistic consideration must be how the wiki looks in the Wikia skin. Some things will therefore not look "right" in Monobook. If you generally use Monobook, we ask that you occasionally look at how your work displays in Wikia. You are strongly encouraged to install this code. It will add a button that will let you easily check what a page looks like in Wikia — but you won't have to leave Monobook to do so.

If you'd like to suggest changes to Monobook, you may do so at this forum thread.

The problem is, you cannot suggest changes at that link, as it's on the old forum, which is archived.

While you're at it, you might want to change the first sentence to say "Most visitors to Tardis Data Core do not use this skin".
