MyBB Community Forums

I was wondering if there was any plugin that would encourage people to make longer, more meaningful posts rather than one liners. Maybe a plugin that gives rep depending on how long there posts are or how often they post, or maybe a points system - the more you post the more characters you use in a post the more points you get.

There are a couple of points systems for MyBB already and you can also change the amount of points to give per post and character, here is the better one and the only one really being developed now, there is also a shop mod for it.:
