We have revised the Support page. It now includes a link to a page with resources in Spanish and other languages.
See the Support page:
http://scratch.mit.edu/howto
Or you can go directly to Scratch resources in many languages:
http://scratch.mit.edu/pages/languages
From there you can find links to more information about contributing to future Scratch translations and resources.
(BTW, I studied Chinese language, so am one of the people looking forward to non-Romanized language support, work scheduled to begin in the fall semester.)
