I know that I don't have 2k of reputation but since a long time ago (I don't remember when) I was able to suggest edition for the questions, just using the edit link below it. After this, a message saying that my suggestion would be reviewed appears. OK.
But today I'm not able to edit any question anymore.
The edit link is off and a label saying that my user profile has not privileges to edit posts appears.
edit: here is a screenshot showing the off link and the label.
