Since we don't funds to hire translators for getting multiple languages translated we want the community to do the translation for us. Its a social network. I can't find any good open souce framework to auto do this. Thinking something like: User selects a language, system displays random sentences and user will translate it. Then other users can vote on how good it is. If it's 100 votes + with 95% yes then it becomes official. Site is in PHP.
Any ideas?
What incentive will your users have to contribute translations? Social networks are built around community and exchange, not getting their users to work for free.
Have you tried the google translate tool for websites?
