The problem with dating sites, is that there are some free ones out there. BUT the problem is that they do not have the money for the advertising required to make them sucessful. I found one a while back that was really good, looked like facebook (different colour scheme and dedicated for dating). But it had hardly any members!
Then there are the fake sites that pretend to have hundreds of thousands of members, when most were promised free accounts... but have to pay for searching/messaging options so leave the site quickly... Paying members then get to see these 'shells' of virtually 'fake' accounts whcih no one looks at or after.
Sorry for putting a downer on online dating, I am sure it works for some but don't expect it to be free and don't trust just any site. I hope some of the other members can point you in the right direction here. I know some have sucess stories from dating sties.
