I've just reviewed this suggested editthis suggested edit. The original answer was short and not of the best quality; the edit drastically improved it, so both I and Mourdos approved the edit.
However, it was proposed by Anonymous and not the post author. That had me considering how to review for some time: drastic edits to posts not by the author are generally frowned upon and rejected for fear of changing the author's meaning.
So, what should be done with edits like this? Did I do the right thing or should I have rejected?
