You have the option to retry.
And I think I will be hasty when deciding.
If I look at the persons application and nothing really appeals to me I don't see a reason to accept them.
The person should be active in game, and put effort into their GM application.
If the application is missing something or the rules were not properly followed then the person should suffer the consequences.
You wouldn't go to a job interview with a bath robe on, as I expect the people applying to not just post their applications when they look bad, and plain.
And the answers should always have personality in them so it's not generic and bland.
