Last week there was a small raffle here in which there were 2 books to be won. The raffle has now ended and the winners have already been chosen. I have already notified the winners Stefan and Michael by e-mail. If one or both winners do not respond within a week, there will be a new draw, so please check your inbox quickly 
A total of 647 people took part in the raffle, not a bad figure in my opinion. Perhaps MITP Verlag would like to make a set of books available for a prize draw more often?
