Translating and dictionary rseources

Hi, I'm trying to translate a small text (actually, a FAQ) from english to spanish, and I'm having some dificulties: I can read/write fluently on both languages, but as I don't normally translate what I say from one to the other language, finding the exact equivalent is not so easy for me. The only translating dictionary I found in SuSE cds is "jdictionary". I understand there are also some online dictionaries, but I'm unsure about their usefullness, and I can't be permanently on line (expensive, and I can't monopolise the phone). Are there more translating dictionaries that can be installed? Any texts or glosaries of common and not so common computer terms? Recomended translation practice? Ideas? -- Cheers, Carlos Robinson
