We've just added a "Thank You" function to the posts which I think will, in the long term, replace the current reputation system.
It is simple... if you like a post, thank someone. If you don't like a post.. either report it or respond on the forums.
The thank yous will be public and will add to a users reputation. However, it will prevent users with high reputations from playing games, as no negative points will be given out.
Lets see how this works...
One of those things I need to test before we go live with our new version (in March... hopefully...)
