BuddyPress.org

Translation suite for BuddyPress (Beta super bleeding edge use-at-your-own-risk release)

http://wordpress.org/extend/plugins/bp-translate/

Includes a multilingual page/post capability for blogs (based on qTranslate), a po/mo editor (based on Codestyling Localization), and a slew of ajax functions for translating BuddyPress core component user interaction through Google Translate on the fly.

Very little support will be offered for this plugin, so use at your own risk. It’s held together with duct tape and glue, so parts may be loose or totally broken for you.
