How do you request a new feature for Yahoo Answers?

Its happened to me more than once.

I'll answer a question, and come up with a really good answer, but then the asker wants to ask a follow up question, and updates the question with "additional details." a month or so later I come back to the question after its long closed and find these "additional details," and think to myself, "hmm, I could have answered that too."

The feature I would be requesting would be either of these two:

1. When a user updates their question with "additional details" all askers get sent a message (preferably an email, with the option to opt out of course)

2. When a user updates their question with "additional details" some sort of message appears asking that user if they would rather send the update as a message (email) to a particular user, so the answerer can get back to them in a much more timely manner.
