How do you say master in spanish?

It has become a habit in Spain (and a bad one too) to borrow Words directly from English into Spanish. This happens especially with new or fashionable Words (or both at the same time) Webmaster is one of such instances. We just do not bother to translate it. In most Spanish web sites you will find the line "Contacte con el webmaster" So if you want to follow the crowd, just leave it like that. I believe the following phraseswould be good ways to translate"webmaster" though (and I hear that they are in use in many web sites from most Latin America countries) Administrador del sitio web (o página web) Director del sitio web (o de la web) Hope this helps!
