Edit Feed...
Forum-Index → Suggestions → Rejected → Edit Feed...A quick summary of the main reasons why:
It allows rule-breakers to edit out things they've done wrong.
And with the 'top of the notifications' function that can be easily abused by advertisers or whatnot. And it's definitely going to be annoying to see the same exact thing over and over and over again.
Solution: Copy and past the feed and fix the mistakes. So you might have to redo BBcode, sure, but it's not that big of a deal.
