loopy love is qute good but its isnt free.
Free ones do tend to be full of losers and strange people - with the ones you pay for you are more likely to find someone genuine - i think its like �29.99 for three months.
Or there is "a place to date" which is free but lots of foreigh people on there wanting to get married for visas!!
I used to think dating sites were for losers but one night i went on google wanting to speak to other parents and found the site it was a fluke really, got a message and had to pay to read it i was intriged and it was all worth it, i was lucky it wasn't some bald fat wierdo, so i can vouch for parentsalready.co.uk but i know not all of them are probably not genuine.
