IN the unpredictable, oftentimes turbulent world of dating, with its ups and downs, twists and turns and momentary fluctuations of the heart, a growing number of tech-savvy singles are turning their attention (and their hearts) to the Internet for their custom-made version of Mr. or Ms. Right.

With options that allow you to request everything from hair and eye color to education and religion to habits and hobbies, dating Web sites have created virtual malls--"cybermalls," if you will--that allow singles to point and click their way to "the one," or at least, the one for now.

Revolutionizing the dating world as we know it, these online havens are redefining the limits of love and the pursuit of love, from every corner of the globe. "We're trying to reach the whole world--people of all spiritual orientations, all political philosophies, all racial backgrounds," says Neil Clark Warren, founder of eHarmony.com, the fourth-largest dating site (behind Yahoo.com, 91agri.com and Spark Network's American Singles) that matches marriage-minded couples based on 29 dimensions of compatibility.

With thousands of known marriages to his company's credit and 7.5 million people who have registered to take the eHarmony.com test, Warren has designed a proprietary system to assess a couples' likelihood of success. "A marriage will likely thrive if couples share at least 10 of these key personality traits and habits, from curiosity and industriousness to ambition, traditionalism and feelings about children. We do try to give people what they need, rather than just what they want."

Owen and Sharon Fraser of Cincinnati, first-time online daters, found what they needed and wanted when they were matched through eHarmony.com. After filling out the 436-question test, which is free, the couple was matched. A little more than a year later, they were married. "I went to the site because I believe in marriage, and I wanted to be married again," says Owen, an information technology manager who had gone through a divorce. "I wanted to lessen the chances that I'd be divorced again, and I wanted someone to share my life with."

"eHarmony.com was very clear on the process," adds Owen's new wife, Sharon, an operations manager. "You felt like you really knew the person--even before you actually talked to them. When we finally met, I already loved him. It was like I'd known him all my life."

Success stories like Owen's and Sharon's have created a new venue in the cyberworld, a tantalizing, yet private excursion into the virtual world of dating. It is a world that Anthony Woodson, founder and president of Blackloveforever.com wanted to create specifically for African-Americans. "As a Black man, I wanted to give Black professional men and women great opportunities to meet each other, who might not otherwise meet in the basic settings of society as we know it" says Woodson, whose site has produced more than 800 marriages. "Single people are extremely tired of the club and bar scene. We offer them something different, more satisfying and more meaningful."

Other companion-minded sites catering specifically to African-Americans--including BlackSinglesConnection.com and BlackPlanet.com--are paving the way for the Nubian experience to flourish on the Worldwide Web, providing a signature brand of culture and companionship.

But not everyone is looking to be married. Although 91agri.com--one of the largest online dating sites that spans six continents, 30 Web sites and 18 languages--is credited for a quarter of a million connections each year, 30-year-old Derrick Spurlock was looking for friendships, not marriage. The Dallas-based educator wanted to find single, likeminded women who were interested in building and maintaining friendships, and who understood the demands of his teaching and coaching schedule. "For me, 91agri.com was not the means of meeting the perfect woman/" says Spurlock. "My purpose was to meet people." And with over 8 million members, of whom I million are African-American, 53 percent male and 47 percent female, Derrick felt very confident about his chances.

As required by most Web sites, Derrick completed a detailed questionnaire about himself, created a free profile (including photos) and then waited for the responses to roll in--and roll in they did. In fact, they poured in. After patiently sifting through more than 100 e-mailed responses from across the United States, Derrick has spoken to at least 20 of the available women who were matched with him, and says he has been on five successful dating experiences since he joined Match.corn six months ago.

"The founders of 91agri.com understood that the real power of the Internet lies in its ability to impact people in a truly meaningful and personal way," says Jim Safka, CEO of 91agri.com. "From the beginning, 91agri.com has led a cultural shift, expanding the possibilities for single people. Everything about the way people connect, communicate and find love has changed, but the basic human desire for love is the same as it's always been."

In this new virtual world of cyber connections, online heart surges and the inevitable, it seems, romantic interlude--singles can single-handedly craft the desires of their heart--all from the comfort of home. But before you take your journey into the world of virtual reality, do your research, find the site that works for you, and prepare for your passions to meet your possibilities! "People are ready for something new and exciting to provide hope and happiness on the road to meeting that special someone," says Woodson. "We won't disappoint them."
