Well, as expected, your application follows the guide lines set and you have the requirements.
Unique comments: "I hope you like my 2nd application!" - Albeit this is being nit-picky, I believe that this could've been changed to claim that you know we would like your second application, as that would show more confidence (in your defense, you displayed such confidence in claims such as: "I am sure I will make the server a happier place if I was helper" (albeit the removal of the words "I am sure" would have made that sound even more confident))
"I believe that being active on the forum is a very important part of being a helper because you will know what is happening right away, not just having someone tell you on the server." - This, mainly I agree with your belief because it shows diligence to your dedication to the server. (Albeit, once you become staff you'll have staff chat, thus you'll have another way of attaining important information.)
"I see disrespect to players, the server, various things. I could prevent that by giving them a warning, and if they don't stop I could mute them and have higher staff (moderator, admin, and owner) decide the punishment." - Yes, I agree that there are cases of such disrespect, however the only one of those that requires reprimands is when players are majorly* disrespecting others*, criticism of the server isn't directly against regulations (albeit, it would be nice to point them to a location on the forum to suggest that these issues that they're critiquing be acknowledged and action be taken upon them.) However, it's the section of your claim about having a higher power decide the punishment that's a misconception, since the punishment is usually outlined in the rules (albeit these outlines are taken leniently.)
"So if I was on I could let the hackers know that I am on and you will get banned." - Letting the players now that they will get banned provides a bad shroud over rule #1 on rules page 3 (do not accuse other players of using a modified client.) As such, it's better to just dispense the punishment (in your case temp-banning and placing evidence of them using the hack on staff chat so they may be permanently banned.)
"some of those people that I helped in April when they were confused and annoyed, they still play on this server." - It'd be great if those people who were exasperated would post here saying how they were helped and their experience, it would light up Crash's appeal - any takers?
-Tip- It may be a good idea to use a word document or some form of spell check, it would fix small grammar / spelling mistakes (of instead of on; regards) that would strengthen the presentation of the application.
