(I have translated some parts with the Google Translator, so the following text could have some mistakes. Sorry for that)
I'm Silver-tm- and the administator of the German SonicWiki. One of your users (Luz Sonic) wrote me a message on Twitter. (The conversation). He said that he uploaded a photo without chose a licence or the owner of this picture. He asked me to delete the picture, but I'm not an administrator of the Polisch SonicWiki, so it would be great if you delete the picture.
