When you think of 100% Free Dating services today, the term doesn't mean what it did a decade ago. Today when you think of a dating service you instantly think of online dating sites. You see them advertised everywhere from every paper you read daily; to the late night ads you see on TV. There is really no way of getting away from being bombarded by dating sites.
If you are single these sites are one of the best ways of meeting singles in your area. You can post a profile and almost instantly you will receive responses from other singles in your area. You can sort through the ones that interest you and nix the ones that don't meet your criteria. It doesn't take long to find one or more profiles that interest you enough to at least respond to.
And here's the beauty of online dating sites; you don't have to give out your phone number or address or meet them in person, until you've spent some time corresponding with them back and forth thru the dating site. The dating sites will keep your email and other information safe so that no one can contact you directly unless you choose to give out that information.
This makes the chore of dating much easier. You can list all your likes and dislikes in a person and the online dating site sorts the profiles according to your list of desired things in a person. There is nothing worse than meeting someone in a bar and getting to like them, only to find out days or weeks later that they have 3 traits that you just can't stand.
In most cases a lot of the traits you don't like in another person will come to light when that person fills out the online personality profile with the online dating site. This weeds out a lot of the types that you wouldn't want to waste your time on. Good luck.
