Re the action for me (Simon Wheatley) to open source my multi-language plugin as part of the “i18n improvements” session.
The Babble multi-language plugin we wrote for and used on Free Speech Debate, is now available on GitHub at https://github.com/simonwheatley/babble. The plugin handles translating posts in all post types and terms in all taxonomies, though the translation of terms badly needs a workflow. Translation of widgets and menus is currently not covered by the plugin, and in the future I’d like to see a much more “work queue” style system for the translation teams in the various languages.
