Hi Stanly,

We have some translations for Spanish and also some for Mexico Spanish, but I'm not sure how up to date they are.

As mentioned in our localization documentation, by default the resources used depend on the browser language preference, but you can force a site to a specific culture as described at the bottom of the main localization document.

ie, you could add this to your user.config then touch web.config to recycle the app.

<add key="site1culture" value="es-ES" />

Hope it helps,

Joe
