I've been married 3 months to someone I met on match.com. I had been on a bunch of dates during the 6 mo. membership I signed up for, but none of them clicked for me. Then 3 days before it expired and I was going to give up, I got a 'wink' from Ben. We emailed, IMed & phoned, met after a week, he moved in after a year, 10 months after that, we were married!

I think it's a great way to meet people if you are honest about what you want and go into it with an open mind. Don't try to be fake and say things you think people want to hear because it'll all come out eventually anyway.
And don't use a picture of yourself that's like 10 years old! That's just false advertising, haha ;)
Have fun.
