ohh, he really didn't say why... I come on one day and he said something about being striped of badges or something and that wasn't worth to continue after so much time put into what he done, I guess.. that's about as much as I know..
I hope that helps a little, i'm sure other's know more about it then me, I kinda just keep to myself..I was bummed he left, but if wanted me to know would of said I guess?
