Right now this pops up:

The wiki is in the process of moving to wiki.qt.io. Please make your edits there.

...on any page under the wiki here: http://qt-project.org/wiki/

Can a line of javascript get added to modify the link at the top of the wiki page to something more useful? Like instead of the home page, link to the new page that represents the same wiki info?

Maybe something like this:

var newSite = 'http://wiki.qt.io/'
$("a[href='http://wiki.qt.io']").attr('href',
newSite.concat(window.location.pathname));
