The only notification one gets that a question they've answered has met with others' dissatisfaction is when it has been deleted and their reputation is reduced. It would be nice if a user, who has gone to the effort to answer a question, would either be notified that it has been closed, or at least be able to search for closed questions that they've answered. This way, they would be given a chance to improve the question before it is considered for deletion.
I would like to request
Each user who has answered a question that is subsequently closed be notified of the closure.
There be a way to search for closed or deleted questions that a particular user has answered.
