The Rules taught a generation of women how to turn their dating misery into marriage success. Dating gurus Ellen Fein and Sherrie Schneider showed millions of women how ''playing hard to get'' could help them capture the heart of Mr Right. Their book proved controversial, sparked worldwide debate and became a publishing phenomenon. But that was all before Twitter, Facebook, online dating, texting and BBM. There are now even more ways to mess up your dating life. Ellen and Sherrie are regularly inundated with messages from women wanting to know: how to maintain a good profile on Facebook, the rules for texting, emailing and tweeting, and how to spot cheaters and players. This is the new dating bible for Rules Girls who want to have a good time dating without getting hurt or played.
