Anything that is free is going to have a catch somewhere. I don't think much of dating sites as there are to many oddballs who pose as real people. No online dating site is worth it. Best to just try and meet real people and be happy. Safe? I don't think so.
Hell no, don't do it. My friend recently met several women through a dating site and they were stalkers and one demanded money to stop harassing him. Meet your future friends only if they can be vouched for by an acquaintance. People lie on line. If this is a picture of you there should be no problem meeting someone as long as your not nuts.
