pos/neg rep notification?

TheKroo: Hello,   Sadly there isn't an effective way to track the reputation i.e who gave you what kind of reputation and where, except backtracking your posts via the "Find content option - that is available at the right side of your profile page. But you should not be too concerned over it. Feel free to post and be an active member of the community, You know, you can not make everyone happy, and as long as you keep your posts constructive, nothing to worry.
