I believe they are very patient. And there may be other reason why they do this. They may be testing the site. I delete sometimes 3 new members a day that sign up from service providers from Asia and other parts of the world who just sign up and don't post. I don't think they would do that without having an agenda. What it is I am not exactly sure. All I know is they are persistant, and I do my best to be the same. I sometimes delete them as they are signing up. That always makes my day
