Finding someone special online has gone from underground to mainstream, with more than 3 million people signing up on some of the top sites. So with that many people to choose from, it should be easy enough to keep yourself safe, right? Not necessarily. When you're picking from the online cream of the crop, keep a few tips in mind. Before you even sign up, do some research on the matchmaking company of your choice. Use a reputable company that has similar interests as you - many niche online dating companies cater to those who practice a certain religion, hold certain professions, and other proclivities. Choosing one that aligns with your beliefs helps weed out incompatible and potentially unpleasant matches. Check the Better Business Bureau for complaints levied against the companies you're considering, and when you do sign up, protect your anonymity. Create a user name that doesn't resemble your given name, particularly your last name. This would make you much more easily searchable, particularly if you give detailed geographic information - also a no-no.
