Rioter: If the question has not been replied to, then by all means one should answer it providing they know the answer. But if the thread has 15 replies and one is from the starter thanking everyone for their help, then use common sense and leave it alone.
Preacherman481: I see your point, but at the very least they need to use common sense when replying to an old thread. If it's technical in nature, great, but if all you have to say is 'I agree' with no real contribution, leave it alone. The whole reason for that part of the original post was the fact that one night almost half the threads on the main page were replies to old threads by newbies who for the most part were seeking to increase their post numbers.
