I am not sure if this has been done before, but I think it would be interseting to know how we all came up with our NPF names.
Walkertexasdruid: It is quite curious, because my name is not Walker, I am not a druid (though through my mostly British Isles ancestry, one of my sires may have been one 2500 years ago), and I have never stepped one foot in Texas (the closest I have been is Alabama, where my grandfather lives). Anyway the name came from a D&D campaign, where I was trying to emulate one of my favorite Terry Brooks' characters, Walker Boh, a druid who survived through five Shannara books. My DM started making fun of my character by calling me, "Walker, Texas Druid". The name stuck, and I have been using it for many of my internet endevours ever since.
The Thread Killer: A very dark side of my personality that sometimes takes over and actively starts mindless threads, and who tries to derail good threads with mind-numbing comments. I try to keep him under control, but sometimes he takes over. My apologies for the things he as done, and the things he may do in the future.
Alright, you have glimpsed into my scarred psyche, in regards to my names. Now everyone, let us hear what inpsired the choices of your NPF names.
