I am finding an increased tendency for people who request information on the light boxes just to disappear into the void after I go to the effort to respond to their requests. Common courtesy dictates, at least in my eyes, that it proper to acknowledge a response and not just ignore it. I know that this is basically a minority, but still I like to know that people have at least received my replies, whether they intend getting a light box or not.
So come on people at least let me know you have received my replies.
