All right.. I did not put it up the first time due to the fact that it is a very stupid reason.. but here goes.
When I first started doing the bulletin board thing it was a fantasy football board and I wanted a 'cool' name, so I picked 'Mack Daddy'. At the time I was young and single and looking and I thought a handle like that might actually help
However, when I came to this board I figured that name did not really fit in this crowd, and honestly, it wasn't me. So I shortened it, and now that is my handle in other boards also.
