I'm not going to lie, I heavily disagree with anyone saying that you shouldn't be allowed to edit your application after receiving feedback/criticism.
This is because of the many communities I've been part of, where admins (including myself), would give feedback/criticism to the applicant, and tell them what's wrong with their application, as well as what to change. Then before making the final decision, the applicant is allowed to revise their application, so that their chances of being accepted become greater.
I guess it's because I've gotten used to it, but I don't see anything wrong in revising your application after receiving feedback/criticism. It is also why I decided to change my post in this thread, and give Firefly a +support. He changed what I disliked, which is what I also wanted to happen, so I changed my opinion.
