Msdis- HMMM not really sure why. I guess Miss I no longer am, Mrs. is too formal, Ms lends it self to a little more pizzaz and it sounded bouncy; and dis for obvious reasons. There are so many great names here but after picking mine I felt I had adopted it, so it stayed. I felt self conscious at first that it sounded snobish but I see others who have taken versions of it so I guess it's ok.
