Little trick, set the content manager filter for "My Content" and you'll see instead of your name, it has a # followed by your own KUID number. To find the name of any author, copy the first part of the number and paste over your number, leaving the pound/number symbol. Example, Author = #45324 which would tell you that number belongs to norfolksouthern37, and since he's the owner of JointedRail, I would look on the www.jointedrail.com website to see if I could find it there.
