If you´re serious then just ask if anyone lives in the same city as you, wherever that is, you will then know who to focus on and who can go screw themselves.
Then you make a move on that girl and BAM, it doesn´t take too much to get her to meet you in real life, once you´re that far, go get laid because that is one of the main reasons she came out to meet you face-to-face and you both have 2 things in common, first is the same city, second is you both are nb members.
This is only IF you´re serious enough and are not trolling.
