On Codex i18n: an suggestion :)
Hello, I just thought that Translate extension can help on Codex i18n. This extension provide an Glotpress-like interface to translate stable docs. This page is an example, the top link Translate this page lead to the translation interface. Though languages must be added prior to users submit translations, just like the wiki concept there is no need to approve every translations by default, that is, the translation works like editing a wiki article.
