That's kinda touching. The story behind my nick is a lot less poetic.
About fifteen years ago, I was trying to join my first internet forum, and every handle I tried was already taken. Out of sheer exasperation, I typed in, 'Windflier', and it took.
The way the software was written, there was no turning back, so that's what my nick became. Over time it grew on me, so I've kept it all these years.
Actually, Windflier is kind of a cool name.
