Imaging that you could know if your new date really LIKES YOU or not BEFORE contacting him/her? So when you decide to send the message you already know one's attitude to you.
Sounds interesting? The new online dating social network LiveDating.me works just like that, and its based on FLIRTS.

At some moment you receive a Two-Way Match and here the game begins
