Before accepting a translation, check that there aren't any comments or multiple translation choices in the main translation as it would corrupt the [1]ratio between the numbers of characters by language[/1]. If needed, edit and move the comments or the less plausible translation choices into the "%s" field of the form.
%s is the name of a form field. [1] and [/1] must surround the translated text, they will be replaced by a link. Field is in the context of text box, input box for an html form.
