Well, maybe if people would actually READ your profile and respect what it says. Mine has very specific distance requirements and yet nobody pays attention to them. I'm not going to even both responding. They obviously don't listen, don't care, or have other motives.
I just started with this online service. I recieved three messages from three different ladies and each one had this: "This user's profile is hidden, please try again a few days later." So, it may be seniormatch's fault. The only one that I was able to respond to was not a match at all. I was not someone she is looking for by her profile. I sent her a message anyway to see it it works.
