So a slight snag on my part. I accidentally posted something with a slight error in grammar and was wondering how to place one of those translation and/or grammar fix boxes you see on some foreign language posts.

Can anyone help me?

On the left side of the screen, under the tag list and the image's statistics is a list titled 'options'. One of those options is 'add translation'. That's the one you're looking for.

you can also just hold shift then click and drag on the pic to add it
