I recently answered a question, and in my answer I had a code sample. I came into the office this morning to find that my answer was modified. I was more than a little annoyed because it was marked as "code indentation" which isn't true, the code was actually changed, and as a result my answer was no longer accurate. Luckily my answer had already been accepted. Besides that, it's bad for the site to have inaccurate answers because someone wanted 2 points.
Since I was the author of the post shouldn't there be a way for me to revert the change? I didn't see anything obvious, I had to manually change it by retyping the code sample.
Also it would be nice to have some sort of recourse, even if it's just the ability to leave a comment to the moderators that accepted the edit and the person that made the edit explaining why the edit was not acceptable. Does this exist and I'm just not seeing it as well?
