Why not just close it to edits?
Deleting stuff that people have worked to put up -- especially show info -- would be an act of extreme bad faith. Why donate any effort to FTL, if Ian is likely to drop your efforts down the memory hole?
I'm not saying I agree or disagree with it. I just work here.
In general I prefer keeping sites live as long as possible for archival purposes even if it's no longer practical to continue maintaining them. But MW is a fast moving target and was becoming a maintenance hassle.
Now for your announcement:
The wiki has been taken offline. Interested people can download a sanitized archive of the wiki software and database from: http://www.freetalklive.com/files/wiki-archive.zip
(In this context, sanitized means your IPs and encrypted passwords were stripped out. Any nude pictures, if present before, are still present.)
