Personally... I'd also just like a way to "bring something back to zero." As often seems the case here, certain random posts seem to get positive of negative APs for no apparent reason.

For example, just yesterday (I wish I could find the post now), I came across a thread that had a single "newbie-like" question in it that had a few positive APs -- nothing else, just the question with not-a-single-answer... but positive nonetheless (rather than "even"). The temptation was certainly there to slap the post with negs to bring it back to "normal," but I know that it'd probably hit it hard, probably even take it to "very negative" or thereabouts... so, I left it alone. In such cases, it would be nice for senior members or, at least people with a given level of APs, to be better able to "bring the post back to center" accordingly.

...and yeah, this has been brought up time and time and time again.
