how do i delete a stupid question?

(A) If you mean your OWN stupid question,

Look at the Delete button just under the question. (“Edit Close Delete More”)

(B) If you mean SOMEONE ELSE’S stupid question,

You should leave a polite but firm comment: “This question is of low quality, could moderators please delete it.” And if a moderator sees it she will delete it.

(C) If you mean your OWN stupid question and you are NOT ABLE to use that delete button,

Leave a comment, “Could moderators please delete this question.”
