Activity - I've seen you in game, but not much on the forums. I cannot say anything about Teamspeak because I'm never on it.
Now for the application:
The introduction - If you apply again, I would like to know more about "you" and not anything about Meepcraft. (Like what you do outside of the world of Minecraft.) I get it, you like Meepcraft and that is why you are applying for the staff position. (You don't have to put anything personal, just like you do sports or...you go fishing with friends etc.)
Why you should be Helper - Wow, um... I know there is the word "help" in helper, but you don't have to say help in every sentence.
Like what Monkeyhead is saying:
Your why info gave me no reason as to why you should be a helper above other people. Give me a real 'why' and I may consider.
Weakness and Additional Info - Not gonna say anything here
TL;DR - Overall the application wasn't long and there was many grammatical errors. (I know, I'm really bad at grammar too) I feel like you need to work on your forums activity and work with other players. Next time, try taking a little bit more time to look over the application. The introduction shouldn't be about Meepcraft at all if I remember correctly. I will not post the +1 and -1 because I recently found out, it is just useless saying it.
