Hi, I was the admin who temporarily denied your application. You can reuse the character story after fixing it up properly, however if your situational question is different then you will have to write a new answer. As Brian said there is no edit option, you have to resubmit.
And to clarify, yes, your application was denied for leaving spaces before commas, leaving no spaces after commas or full-stops, errors with capitalization of words, and new lines in the middle of a sentence. We ask that applicants display their best English writing ability as this is a typing-based English RP server and therefore following the rules of the language is important.
