Frontend translation services for EasySocial, etc.

We would like to operate a multilingual frontend for our various StackIdeas extensions (ES, ED, EB, etc.).

Has anyone tried GTranslate to do so? I'm especially interested in how it would handle the EasySocial frontend.

If so, are you happy with how it translates and the speed?

Or, would you recommend some other translation service (I see Microsoft has some kind of translation service).

Thanks. -- Rik
