Extremely dangerous. That said,...I must admit sheepishly that I met my DH online. I saw his post on a Christian message board, and replied that I lived too far away to be more than a friend, but would be happy to email from time to time, IM, etc...
Four months later he sold his house, moved to my town, and two months after that we were married. Our friends all gave it six months. That was 13&1/2 years ago.
Just be careful,...O.K?
