Maybe you could give more points to peeps who start new threads that have many replies? And on that basis, take away points from those who reply to threads that are months old!
Also, could you give me a price on the dedi I have? i may want to keep it for a couple of months and see how it goes. Funny thing is that i haven't even used it all year but now I may have found a use for it, but not sure yet.
