My screenname is a derivative of my real name (although noone calls me Bennie in person). When I worked as a computer analyst I had to make up a fake name to run through the programs. At the time I used parts of my nephew's first and last name. Years later I used Bennie and my youngest son's name as my fake last name. I'll use my "fake" name for junk mail. It's amazing how your name is passed along to other companies.
Since Bratcat rarely posts, I'll tell you that she is a brat 
and she loves our 3 cats!
Nonamejames chose his name when he wanted to join us in the chat room one night. He was trying to come up with a good name and couldn't think of anything. Hence the "no name" part. And James is his name.
