I voted for this one
"Because I think they also will like what our community has to offer"
Although it is the best answer from the choices available my reasons were a bit selfish. Mainly my true reason was that I was too lazy to explain to them how to properly play poker instead of facebook style. So i was just giving them the link with the words here you can learn a lot more then i can teach you and you can also get 50$ for free to get you started. I must admit i was a little bit disappointed when some of them didn't even bother to pass the quiz.
