My choice of screen name is based on DonQuixote ,my favorite character from my favorite novel.The 66 is just a number.I mentioned in another thread we should have a thread with this title. I have already been PM'd asking me to start it. So, I'll go first.
MrFSS is short for Mr Financial Settlement Services. That is a subsidiary company of the big company I retired from a few years ago. We only had a few employees in our little group, and to many of my customers I was know as = MrFSS. It stuck and I keep using it today. Haven't worked there in a few years, but I still hear from folks now and then.
So, if you have a story as to why you have the user name you use and want to share it, this is the place!
