Add a link with accepted application so people will be inspired by them, or so they know how to make a good application. It's really helpful. Also, if this will be added, there should be a rule saying: Copying someone's application, will make your application close and you will be banned for 1 day. (If it needs to be something different, let me know. )
Your suggestion didn't really make sense... 'Copying someone's application,' well, a lot of that happens, and it goes unpunished and/or unnoticed. In my opinion, applications should just be locked for staff's eyes only because there is no way to copy what someone else said.
What do you mean a link? If you mean a sub forum topic where accepted applications go I think that would be a great idea.
Honestly, applications shouldn't be public at all. People can copy, get feedback, and resend applications whenever they want. In fact, the whole section should be temporarily closed, especially if they aren't actively hiring right now.
