Don't quit after a few weeks, just keep contacting new members. There are lots of different online dating sites and many of them are free to join. Be wary of completely free dating sites though as they often encourage time wasters and undesirables. Most online dating tips for women over 40 sites let you join for free allowing you to browse profiles. However you have to pay a joining fee if you want to contact any.

The more you smile, the younger you look. It's true. I was out at a nightclub with a couple of girlfriends not too long ago and in the group, the ages ranged from 27-46. And you know who got hit on the most? The 46 year old! Most of them men that flirted with her could not believe she was 46 and they ALL commented on how beautiful her smile was. So, keep smiling and you will appear much younger.
Don't keep sending messages to a member if she or he doesn't respond. This can be annoying and put most people off from contacting you back. You may come across as being needy and desperate!
It's amazing to me how many people I've met, and even some of my own closest friends, who are a bit....let's just say, LESS than totally straightforward with their dating profiles. In my view, one of BEST signs that someone is really ready to settle down, is their ability to genuinely communicate who they are, what they want, and what they're looking for.....warts, flaws and frailties included. (We all have them, right?) Why put a picture of yourself from 2002, or list yourself at the weight you'd LIKE to be back to....or even your height with 2 inch tuxedo heels? Being honest is very sexy, and in my opinion, is the baseline from which lots of other special stuff springs forward, too.
You can believe that you have all the bases covered then the next thing you know you fail to notice a small detail. As far as you are concerned its trivial. Not to them. It doesn't mean that you have to continuously store and regurgitate every bit of information they share. But pay attention to what said information means to the other person. If they repeat the same thing in the future be ready to expand on it.
