gamification question

Hello,

Is there a gamification plugin that I could setup on my community where “points” are earned for every time a member posts content, shares a link to content, or comments on content/comments/posts/shares.

I’d also like a member to receive points anytime somebody “likes” or “shares” anything that member posted (comments, likes, shares, posts, etc…).

I know there’s plugins that will give points for visiting the site or creating a group or making a friend.

What I’m looking for is a plugin where points are actually based on merit and not just someone coming to the site. That way if someone has 100 points – because 100 other members “liked” their post they’d become a “subject matter expert” – 500 points and they’re a “thought leader”….something like that.

Anybody?

Thanks!
Rob
