Thread:Project:Support desk/Howto use wiki with different skin?/reply

There's no way to do that unless you use a JavaScript code that would propagate the ?useskin= on all links, but it may eventually fail (specially on forms, like Special:Search and redirects).

A safe solution would be if you can set up another subdomain or path, you can duplicate the wiki installation (either with symbolic links to the current installation or with alias/redirect on the server) so you can access the wiki from 2 different subdomains or paths (for example: example.com/w/index.php and example.com/i/index.php). Then change the default skin in LocalSettings for the second instance. Then you would have the flexibility of setting this instance as readonly, so no edit links are presented, etc
