Wow! I was surprised to read that. Being a resident of Arizona, EVERYTHING here is in English AND Spanish. Goes to show how much we assume! As long as it takes Ubuntu to load and install the Language Packs, you would think that Spanish was included?! (or are we talking about support forums/documentation?)

Have you tried Google Translate as a 'bandaid' for the lack of Spanish support? Obviously, it doesn't negate any lack of native support for your language, but maybe it would help until the Linux community wakes up to your needs.
