Throughout the Maths questions, we can see many answers which have not been voted as desired or corrected ones yet. Do we need an alert or something on the page notifying the questioners pick the best answer soon? Note me please if this was asked before in any other ways. Thanks.
We don't need an alert - but there's nothing wrong with someone leaving a comment politely inquiring as to whether the questioner has had time to consider the answers on offer, whether the questioner would like to ask for some particular point to be further clarified, etc., etc.
