I think we should be able to earn "points on game and forum." You get points for being nice, helping others and so on.
Only co-owners+ can give points. These are some rewards from points.

1 point: 25 posts on forum
3 points: 90 posts on forum
5 points: 150 posts on forum
6 points: An admin can spawn you any non-rare item.
10 points: 400 posts on forum
20 points: 1000 posts on forum
20 points: Have superapply *
20 points: Upgrade from mod to admin if you've been mod for a week+
* superapply is basically being able to get mod after you apply.

how can i make like an auto point systeam for fourm?

You could acheive that with custom portal fields. There was a guide for that in the Guides and Tuts section. I think it was called 'Guide to creating a rewards system' or something like that.
