One day, I wanted to play Minecraft. So I bought the game, and that then charged me with the task of finding a screen name. I tried Builder59, but that was taken. I still wanted a name with 9 in it and also apparently weather came into my mind at that moment. It then branched into rain and the sky. And since up is the direction of the sky, and raining upwards is an odd occurrence, my screen name became rainup9. Fast foreward a few months, and I simplified it to RAINCRAFTER.
