The wiki.webkit.org address still redirects to opendarwin.org. It should redirect to trac: http://trac.webkit.org/projects/webkit/wiki
I can fix this temporarily via a redirect as the A record for wiki.webkit.org is still pointing at my server (the one that also hosts the nightly builds). Ideally this would be fixed by changing the DNS entry for wiki.webkit.org to point to the same place as trac.webkit.org and doing the redirect on the macosforge end. I'm not able to do the latter, but I think Tim may be able to.
I have put the temporary redirect in place: RewriteRule ^/(.*)$ http://trac.webkit.org/projects/webkit/wiki/$1 [R=301,L,QSA]
Fixed. It redirects to the trac.webkit.org wiki now.
