Hey Nick! I'm going to try and keep this simple.
I didn't want to previously comment on this because I hadn't officially met you that well yet. The best I've done was seen you around. Fortunately, that changed today.
From me seeing you in game, I haven't personally seen you be very mean, or rude. From what I've seen today, however, I think I can give a clear vote. My general impression of you has been very good so far, and I think it will stay the same. You've helped in shout; i'm quite sure of it. Your forums activity recently has been good from what I've seen, and you've posted around quite a lot. I don't think I've talked to you on teamspeak before, I've only seen you on there.
In your application, I get the impression that you are on the right track, you've even listed out some important things.
It seems like you've already learned your lesson from before, and I'm confident that you can become a staff member again. This time for good.
