I have started getting yellow notifications of flagged posts. For example, this one.
When I look at the original post I see that it has been closed. On the 'flagged' page the only option is a button marked "flag or disagree" and below it a comment that says:
Please explain the nature of this closed question via a comment
When I click the button I get a page that offers me the chance to flag the post - but it appears already to have been flagged (else why is it in a 'flagged' page).
I'm confused how I should respond.
