Please notify us when a reputation recalc occurs
Last time I logged in to Meta Stack Overflow, my reputation points were over 400. Now it's back under 300, and I don't have any idea why. One possibility is that I have a vote fan who committed vote fraud on my behalf on Meta Stack Overflow (probability of this is near 0, I think). Another is that there was a reputation recalculation triggered somehow, but since I haven't been too active on Meta Stack Overflow, I cannot image that having a serious impact. Yet another is that there is a new limit on points from asking a question (many of my recent reputation points came from a recent question I asked). Or it could be something else entirely.
While I would really like to know in this case what happened, just for curiosity, it seems like it might be a good idea to let users know the reason for a drop (or increase) in reputation points of more than 100 points or 20% or some other reasonable threshold. My guess is that there are a limited number of reasons for such a sudden change, and having a message in my Stack Exchange INBOX tab at the top letting me know the reason would have been nice.
