Well, I have posted under other names when I was teaching, so that my presence on this board would not be an issue for students, and when there were things to say that for various reasons (somtimes to protect others) I could not say under my own name. But I have never "answered" myself or tried to puff up a thread that way, and I think many other posters could say the same. If USM was the place it should be, everyone could use real names. How many trolls have used multiple or real ID's??
