Best options for translating a rails app

Since there are so many options there available for internationalization of a rails app, which gems or plugins are the best (today) for adding i18n support开发者_开发技巧 to a rails app.

Im using I18n bundled with rails for the application messages, button labels, and model attribue names.

But I also need to let the users to input content and the translated version of the content, but there are so many options for this right now that I don't really know which one to use.

We at Mynewsdesk (the guys behind the translate plugin) has moved on, now we're using Web Translate It to manage our locales. We've bloged about our translation workflow.

I like this one: https://www.github.com/mynewsdesk/translate

because it has a nice webGUI for translating new/changed strings
