Can there be a way to "lock" questions?

Question

By this, I mean make it impossible to answer questions that have been resolved, possibly when Best answer is assigned. It's kind of annoying when older questions that have already been resolved get answers that don't contribute anything new to it. We don't need to hide the questions obviously, but preventing new answers would be helpful. If the question is resolved, but there's proof the answer is incorrect, then someone can leave a comment and changes can be made for it.

Answer 1

There isn't anything yet, but I'm hoping this will be possible soon. Instead of a complete lock, I would probably limit it to more experienced users, e.g. people over 2,000 points could answer. They would know to only answer if the current answer became incorrect or they could improve upon it.

Comments

Once you see the "hidden" list, you'll know why I asked this.
