I personally don't know you (considering I left PRP for SCP-RP a month ago) But what I can tell you is that MAJORITY of this app is very well put together. I could nitpick at some smaller things, but I will discuss that in a minute. You having previous experience is a plus, but beware, players here can get out of hand sometimes. I think you'd make a good addition to the team.
However, as I said I would go over my nitpicks. Your question 16 is very vague, almost to a point of you wouldn't try to do anything aside from "calming" them down. To what degree? How would you calm them down? How would you take being cursed at, or yelled at? What actions would you take prior to calling an admin+ to come administer a 10,000 second minge? These things need to be noted.
You also don't have a poll, which is detrimental to applications of any degree. Regardless of what it is for. Be sure on future additions to applications that you add a poll.
Last thing, keep in mind that everyone needs to be fair in a sit, regardless of what an outcome might come to be. You stating that you handle sits decently enough to satisfy players with the outcome. This could be a very crippling flaw over time especially if you have multiple people. Notice I said "COULD". Don't let that ruin you as everyone needs to have a positive outcome from a sit, nobody should be treated differently (unless they are a huge minge and don't care)
Either way, good luck to you sir!
Note: As Sion said Number 10 is wrong, it asked a blatant question. Also increase your forums activity that would definitely be a huge help.
