I believe you will be a good addition to the team. You are very mature and calm, two qualities that are very much appreciated. I've seen you handle situations as a non-staff member and I have to say you do a very good job. You don't shout at them or something like that and instead, you approach them respectfully and explain why their actions are against the rules, in such a manner that actually leaves a mark on them and prevents them from doing any future rule break of the same sort.
Therefore, I support you.
