There has been an edit to an old answer of mine and it was approved by other two users. Now the answer is wrong, obviously.
What should I do?
I'm not happy about this at all. How can it be that some people make my answer wrong without giving me the chance to explain? Also, if I remember correctly, many edits, in particular by other people, make the post not "mine" any more but some community contribution. This is my highest voted answer, and I really don't want that to happen.
