I have found similar screens occasionally when trying to link through some of my more ancient bookmarks. Sometimes googling some distinctive content (if you can remember any!) is enough to find the new location (if one exists).

Wikipedia has this article - Internet Archive which I thought might provide a way of getting at information from no-longer-extant websites. At least, that seems to be the aim of the project.

Just a thought - I know the DigiTrad has at least one occasionally-updated mirror site here:- Yet Another Digital Tradition Page but I don't believe there is any equivalent for the Mudcat Cafe itself. Could there be? Should there be?
