I want to know if we can add a new feature to automatically lock questions within a few minutes of an answer being accepted. It has been my experience that rarely, if ever, anything constructive comes after an accept. Either people start posting answers **even after an accept**, or post comments that go off topic or challenge the answer (usually erroneously), or things just get out of hand with random discussion. 

I understand thanks to the first answer I got where this would be an issue. My question then would be, does anyone have any ideas of how we can prevent the above scenario as I seem to encounter it frequently?
