I don't think that the fics should be rejected completely when there's only a few errors, such as the submitting to the wrong category, slight punctuation errors (I don't mean repeated mistakes throughout the fic, as the rules say), accidentally centering the fic...and so on.
I think that they should be approved anyway, if it's only a small error, and just tell the author to promptly fix it, instead of resubmitting it and having to wait even longer. Plus I think it would be better for the Mods, so they wouldn't have to read the same story over and over again, and it would keep the queue shorter so more stories could be submitted faster.
It's just what I thought might make things simpler. For everyone.
What do you guys think?
