I raffle off one printed and personally signed copy of my Understanding Network Hacks book!
All you have to do is drop me a mail to email@example.com with the subject “Win the book!” until June 13th 2015 and let me know why you should be the one winning the book. You can be as creative as you like and attach a short message, photo, link to a video whatever.
I will contact the winner to get your postal address and personal message, which I will write into your book. Good luck!
