That could easily be abused by trolls. But I see the point, especially for forum games.
Like everyone said, if not for the trolls, it would be okay.
perhaps only people with over a certain amount of points could use it. I know this has it's own set of potential problems, but it would eliminate some of the trolls at least. Or make it possible to ban people from using it, like the forums.
I'm going to paraphrase what I said earlier, but points aren't a really good way to decide who can do something. A lot of people don't find points important and don't work to earn any. I used to confine myself to the forums and didn't read any stories except for a few rare instances for a few months.
