Not a horrible attempt at an application. I would say that it needs more body and could be more descriptive (Via the specific times you can be active) and one of the questions is cut off. I have personal experience with Night Light and just from what I've experienced: He whines every time he dies,(Bad sport) He's immature, and I wouldn't currently be comfortable with him becoming staff at this point (in my opinion as a server player)
To tell you the truth, I can't expect more from a 10 year old. I don't want to make him seem stupid because of his age, but there's nothing that points to intelligence here. I would be fearful of the abuse that might occur based on his past behavior, (The complaining and verbal conflictions after dying). The person he is seemingly complaining about again here is me, probably from when I fought him in-game more than a few times, and his 'Jailing to reduce MASS RDM' answer seems directed at me as if he is using this possible job as a way to get back at those who have had minor conflictions with him. (Just a thought)
For the safety of the server players, I would want this application to be denied. But I would be more than open-minded to check out an improved application if he reapplied in another 2 weeks.
