So, we're all unique and have chosen our own internet identities and so forth, but there is a reason we each chose different things to call ourselves here. A lot are obvious and relate to your names, or specific CPs. But even then--why that CP? Why is it more special--more personal to you--than others?
So, why choose the username you have? What are its origins? What's the interesting or uninteresting story behind it? What is its meaning to you? How does it describe you? How, in that one word, did you plan to give a sort of "first impression" to everyone?
Mine's not all that exciting--it comes from the years I spent playing real-time-strategy online multiplayer games. "Agent, Ready" happens to be one of the things the Spy unit in Command and Conquer: Red Alert 2 would say when you clicked on him. I kept it around just because I was too lazy to think of a replacement.
