While looking at site blogs on a recent moodlebites course, i realized i couldn't easily understand many blogs not written in English. It was a real shame as i saw lots of comments going on there.
It would be really useful to have an ajax link that says 'Translate this'. This would translate from the poster's (content creator's) language to the logged in users language. Or perhaps automatic language detection could be used.
Either way it would be really useful to have this translation component to help with cross language comments/posts/blogs etc.
(if it was really cool, it would be a full translation engine!)
