Or for every person he downvotes he'll need to upvote another person to keep his points the same. But since this is trial run, I guess it's worth seeing how well it works.
This may sound like a weird request, but is there anyway to show "certain" points? For instance, I don't want my participation points shown. Personally, everytime I see my points go up, I'm like "oh I wonder who rated up one of my post". Then I get the sad realization that I got +1 for logging in. Plus it's nice for me and probably the person looking at my score to see and immediately know that my points (however high) are from my posts in the Technical threads, ie. I know what I'm talking about
