I have been on a certain forum that used first names and the result was certainly not more polite and was, in fact, more creepy. It imposed a sort of false friendliness that was belied by the behavior of those in charge and was used, I felt, to foster the ability to manipulate and subtly control people. People here at MC reveal themselves through their words and actions--that should be sufficient. My screen name and what I say here are as important to me as my birth name, and I am as protective of my reputation here as I would be if my birth name were being used. I don't think it's appropriate to demand someone's parent-given name unless they want to share it.
