So, @Dave84311 @Liz @arunforce I think you should read this.
Firstly, all haters and flammers, look away immediately!
Now, my suggestion is:
In games sections (CrossFire, Combat Arms, Minecraft...) many people make threads asking for help about a certain problem.
My idea is that the maker of a help request thread should be able to close the thread himself and in the end choose the person from the thread who helped him most (can be more than 1 person), which would finally lead the chosen person to getting +rep because many people around MPGH help alot, but many selfish people just want the answer and there's no award for the solver. Although it's only a newphags opinion, I'm sure many people (with common sense) would agree with this suggestion.
