If you've decided to pursue a relationship by signing up on one of the many online dating sites, then you might wonder how best to maximize your results, attracting the best matches - and weeding out the duds. First of all, choose the right site to use. Some sites, like eHarmony, are geared toward those who want to pursue long-term relationships, while others...aren't. Consider the commitment you're potentially willing to make before signing up. With that in mind, the first thing you likely will be asked is to come up with a user name or "handle." This is the name by which potential dates will identify you. It's not a good idea to use your real name - keep it private and anonymous until you find a match that you want to date. Your tagline is next - make it original and fun. Take a look at your "competition" on the dating site and critique their profiles. Note the eye-catching, engaging aspects of other people in your demographic (same age, sex, religion, etc.).
