Check out Vanilla Forums, they have this system were you can like / disagree / hate / vote up / vote down a comment or a thread, this would be really cool to integrate in toribash forums! ALSO each player should have there own wall (sorta like face book) where they can post what ever they want

We already have a system where you can rate threads. As for comments, we had a system like that before but it was removed because people abused it.
A "wall" thingy for the usercp is doable, but i don't get why that would be useful.
