I wrote a page http://en.wikipedia.org/wiki/Wikipedia:Translate_us to offer guidance to translators wishing to translate Wikipedia articles /from/ English to other languages.
You may wish to have that translated for your own languages; or to "interwiki" link pages which already exist for that purpose.
The English guidance for people translating from other language Wikipedias /into/ English is at http://en.wikipedia.org/wiki/Wikipedia:Translation.
