epiphany212: Yes, if you edit your story, it does get pushed back in the line of waiting submissions. Unfortunately, that's the way it's working. If your summary meets the basic criteria needed in order to get your submission validated, like proper grammar, punctuation, spelling, etc., you can wait after it's validated to make some little changes.
GinnyPotter: It usually takes between five days and a week to get a story validated. We're a bit short staff at the moment, but we're trying our best to keep up with our duties, so please be indulgent. If you see that your submission has been sitting in the queue for far too long, then you can always PM a mod about it to see what can be done. This question has already been answered in previous Ask a moderator threads, so next time, please search through them before asking a question to make sure it hasn't been asked before.
