Yeah, I won a book !

What did I do to win ? I just attended LinuxWorld NL :-) I don't know exactly if this was based on luck or whether I was subscribed to some of their presentations or whether I met Jo De Baer to thank him for his help on mrepo's youget. Maybe all three of them ?

But this is what I got in my mailbox last week:

The attached note below says:

Congratulations, you have won a book.
