Please show us when we lose an accepted answer
I've been using SO now for about 6 months and I've had 2 or 3 occasions when I've noticed my rep has dropped by exactly 15. My only assumption is that somebody who previously accepted an answer from me has revoked it and (presumably) accepted a different answer.
I don't have a problem with people changing their minds nor do I have a problem with losing the rep if another answer is closer to what they need. My only frustration is I can't find a way to see which question so I can see what my answer was and what the new accepted answer is.
Sometimes I know an answer I give possibly isn't the best but it "works for me". Because of this it would be really useful if I could track when an answer I've given has been revoked, so I can go back to the question and perhaps learn something myself from whichever answer (presumably new) the OP has chosen to accept instead.
