Hey guys, My name is Rquerd and I am looking for someone who's willing to make a live stream with me and a couple of friends. Please contact me on twitter @Rquerd. We will take care of the art and advertising. All we need is someone with experience on Twitch or Hitbox. Thank you and hope to hear...
