I've seen it happen a few times now where an interesting thread from years ago gets resurrected by a typically new user and then flooded with "necro" posts before ultimately being shut down.
To prevent this from happening, and encourage fresh new topics without drudging up old hat, would it be...
What is the policy on old threads here? If there is a topic I want to talk about and a thread does exist and its like 3, 4 or 5 years old what do we do? Do we start a new thread or bump the old one?
(I used to know this rule but I totally forget and I don't see it anywhere)
