I originally used my full, real name, but realized I might be exposing myself to needless problems. Since this forum has a large number of relatively young (35 & under) posters, and I'm closer to their parents in age (and even older than some), a lot of them started calling me Mom. When I changed my name, that just seemed to fit. However, Tramp can still call me Mistress Marcia, and a few more mature (i.e. old) individuals call me by my first name.
