when I first signed onto AOL way back when; all the screen names I liked were taken. I got so frustrated that I ended up using the screen name they assigned me: B = first letter of my first name, K = first two letters of my last name. It was followed by a bunch of numbers. Had that one for a couple of years when I finally changed the numbers to cats. That helped because I was also a host for AOL Grandstand.
When I registered on this site, I knew there were quite a few from the old AOL message board and chat room days, so I just used the same screen name for recognition.
