Welcome to the board. I, and most of the other readers like to know to whom we are responding. Using your first and last name is a courtesy which we express to each other. You, of course, have a choice as to whether you want to use your full name. We have a choice as to whether we want to respond. Many posters using only a first or ficticious name, have something to hide. I am sure that is not true in your situation. I would also like to meet you at the next convention and there are many, many Mark's in this group. Which Mark are you, Mark? Certainly not a question mark.
