Dear the DRUID Conference team, Let me thank you for organizing such a high-level event. I am proud to participate as a paper presenter. Possibly I am not alone, and you already know, but I have to inform you that there is an issue with downloading the certificate. I would be excited to see and share it with my loved ones. Please accept this letter just for informational purposes and ignore it if a solution is found. Sincerely yours, Saken Kazhenov Ph.D. student at School of Management Politecnico di Milano Via Lambruschini 4/B - (Building 26/B, office 316) 20156 Milan - Italy Tel: +39 329 657 0609 Email: saken.kazhenov@polimi.it<mailto:saken.kazhenov@polimi.it>; saken.kazhenov@gmail.com<mailto:saken.kazhenov@gmail.com> Skype: saken.kazhenov [https://docs.google.com/uc?export=download&id=1LJD3CNayoSGdRcg1nzT7UwDKdznPNX4p&revid=0B6L5B27P4tpjODd4TG40bGhoMTFYbTlTZno2d1VSOUxNQlRNPQ]
