Thread:Project:Support desk/Contacting wiki administrator

Hello, I'm trying to contact the administrator of the following wikimedia website : http://cubeworldwiki.fr/ But I found no contact page or any other way to talk with him. I already tried to whois the domain name, but it seems that this guy used fake addresses to register : http://whois.net/whois/cubeworldwiki.fr Anyone can help to find and contact this guy? I want to suggest him to add some widget to the wiki.
