I got the responds from Roumantchouk directly. The first time I sent an Email was at tsnigri@tsnigri.ru as everybody tries to do. Four days later, I recieved an Email from Roumantchouk answering my questions about his signature on the summary document.
I cannot explain why I am the only one that recieve answers. Probably the emails are filtered and I suppose that I was lucky that my first Email was fowarded to Romantchouk. All following communication were made direcly to Roumantchouk Email. I always added a Russian traduction in my Emails.
Do you have a copy of the email I sent yesterday?
I can Guarantee you that the answers are not fake and come from Roumantchouk.
