BEST PLACE TO MEET SINGLE WOMEN www.eHarmony.com What's the hardest part about meeting women? They're pretty much always on the defensive. Internet match sites may not eliminate feminine defensiveness, but the good ones can reduce it significantly by giving women (and men) power to accept or reject at will. eHarmony.com is among the good ones, mainly because of extensive screening at the front end. More than 400 questions in almost 30 categories helps build a detailed profile that increases the chances you'll hook up with someone compatible. It's not the cheapest match site ($50 for one month; $250 for a year), but eHarmony boasts it has put together more engagements and marriages than any similar operation. (But who's keeping track?) The site is the brainchild of relationship guru Neil Clark Warren, a psychologist who has also written many books on the subject.
