Important is to see how your mutual correspondence is developing, about what kind of subjects you both are talking.But if the woman starts (in an early state) with questions concerning money, for any kind of reason, than you have to be careful and you have to analyze if these questions has anything to do with the situation you and your correspondent are aware of.One of my favorite quoted expression is: "By failing to prepare, you are preparing to fail."

Any person can signup here complete anonymous (use any free email address and fake personal information).
Even when you have to pay to be a member (for receiving emails) on these free dating sites, don't use it if you are serious in looking for a new life partner.For example, some web sites have over 20.000 profiles, however this is not a reason to find any scam inside this Agency, it only gives you an impression how many profiles you can find on the 'entire' web.So, the chance is present, but if you prepare yourself in a proper way, the risk of being scammed can be reduced to almost zero.Only use real, professional and verifiable agencies.Check the agency If you visit the website of some Dating Agency, try to read all the information about this website before you start to browse through the ad's.Perhaps their introduction or 'About-Us' pages or other relevant pages could give you some background information of this specific Dating Agency, which could give you a 'good' or perhaps 'wrong' feeling about this site and their services.
