Ideally, if you could also make an English language statement on your site or blog, please do so and give us a link (in an edit or comment on this page: Statements from producers and copyright holders). In this statement, you could describe whether your content can be reuploaded/translated, and if yes, what are the conditions (how does one credit you, whether it's strictly non-profit, etc). Here is a great example: http://electrocutica.com/faq#oversea
