I received a Flickr message from microsoft_contact tonight telling me that I have published some photos under the BY Creative Commons license and "That is why, for its new website, MICROSOFT will offer free downloads of your photos on the following French site www.personnalisez-votre-pc.com to be used as screen savers."
They insist that they will mention my name and put a link to my flickr page and to the licence, and that if I do not object within 15 days it means I am in agreement with these terms.
I fail to see how I could object given that they do more than the license require, but that's nice from them to ask!
I found one here which is BY-SA, not BY. I don't know if they used more.
That warmed me up while being trapped in Dublin by the snow.
