jbibiza: Just like some guys will try to B.S. you in a bar, the same thing can happen online, but easier as you can´t see them but in general most people are pretty cool. Good Luck!!!
If they claim to be from the same place as you, ask them what their favourite local is.
That's shut 'em up quickly.
If they're Africa, Nigeria, or Russia, ignore it. They're not part of the Connecting Singles network due to major scamming problems.
