finding someone can be hard for people for many reasons, all your friends have partners and their friends to , so no introductions that way , you maybe a working parent so getting out the home can be difficult , to name just possible reasons for looking online.
there are both plus's and minus's of internet dating as there are on any form of finding someone special to spend your time with.
However any site wanting to charge for introductions , membership or the ability to communicate with other members has to double and tripple checked .
I would advice checking out the free sites if you are to go the internet dating way.
Also please rememeber many people will tend to post an old photograph so they will look better than they do in person , also some married partners will try to use these sites to cheat on their partners. And be sure that you meet in a public place if you do find a possible match , as well as making sure someone knows where you will be and who with , better to be safe than sorry.
good look with your search
