It would help out a lot if you were to put the application template into your app. I'll add the information you have already given to the template below, feel free to use it:
[b]Steam Name:[/b] UglyMehdick
[b]Link to Steam Profile:[/b] https://steamcommunity.com/id/UglyMehdickLmao/
[b]SteamID:[/b] STEAM_0:0:104364764
[b]Link to GameTracker for the server:[/b]
https://www.gametracker.com/player/UglyMehdick/play.zarpgaming.com:27017/
[b]Languages I speak:[/b] Czech and English
[b]Explain "Random Death Match" and give an example scenario:[/b]
RDM is starting shooting someone for no reason, and it is warn'able
--You need to put an example of RDM here --
[b]Give three examples of an acceptable KOS and its scenario:[/b]
a) Player1 [Traitor] : Player 2 is a traitor!
Player 2 [Proven Innocent] : False KOS, KOS Player1
b) Player1 [Innocent] : KOS Player 2
Player2 [Traitor] : Why?
Player1 : You went past unid'd
c) Player1 [Something] : KOS Player 2 for KOS'ing innocent!
[b]Give two examples of unacceptable KOS and their scenarios:[/b]
For this section you need to explain 2 things you can't KOS a player for, an example would be "He was injured".
[b]Why I should be chosen (we recommend around 100 words):[/b]
Actually, I don't know myself but I can try? I will also need some help since this would be my first time being staff ever.
For the acceptable and unacceptable sections, it's much better to lay it out in the following way:
You cannot KOS a player for being injured. Scenario: PlayerA calls a KOS on PlayerB because they are near death.
I recommend you change the scenarios you have already given to follow this format, it makes it a lot easier to understand.
The "why you should be chosen" part could do with a lot more detail too. Explain why you want to help out and be staff. Oh, and don't worry about never being staff before, you'll be trained and know exactly what you need to do.
Good luck!
