This discussion is related to the Old Posts
I have just released my latest plugin Old Posts, this is designed to prevent users from posting on very old discussions that they may have found with search without consciously choosing to bring up the old discussion. Many users don't realise how old the thread is.
If you have any problems with it, and there most likely will be bugs then let me know.
