I just had a strange thing happen. It was revealed that I had a typo in one of my own answers regarding a reference number (chopped off a number). So I went into my answer to fix it, and when I went to save, it gave me all kinds of prompts about the edit not being more than 6 characters, no edit summary message, and when I was done it prompted:
I thought that odd. I refreshed the page and saw I had a "Review" task... which was to review my own edit... I approved it?
I've not had this issue before, and my rep has been high enough to edit pretty much anything without prompting.
Did something change?
