I saw a little red flag near the top of my StackOverFlow browser window.
The message said that someone had edited my message to make it more clear.
There were, I think, (this was yesterday) two options; (1) review and (2) approve.
Since I'm so smart and know everything in the world better than everybody else alive anywhere on planet earth (oh yeah) I thought that I needed to stop this malicious tampering at once.
Turns out the guy was a stranger and an angel; corrected four little clueless newbee glitches I did, and made the thing ten times easier to comprehend.
So, I thought I would "Approve" his edits.
BARRRRRRRNNNNNNK !!!!! Penalty. You can't approve edits with less than 2000 points
At that moment, I think I had 80 points total.
It was an interesting experience to be offered the option of approving the edits to my own post, and then when I approved them, to be immediately told that I'm not allowed to approve them.
