Seein as I removed the website I will post some tips for knowing if a girl is attracted to you-
1) If you are walking down the street, or anywhere where you might walk past a girl, if they go to play with their hair after making eye contact with you, they are 90% of the time initially attracted to you.
2) If you havnt met a girl before or know her very little, and she is touching you alot, you are in there. Girls will not touch guys they have met for the first/ dont know very well time unless they are attracted to them.
Also-
3) Do not fear rejection. The guy who gets rejected the most is the guy who will have most success with girls,because i) he would have approached more girls anyway and ii) will have learnt not to fear rejection and come acroos as a much more attractive guy due to increased confidence when attempting to chat up girls.
