Ever since the site redesign and the addition of the similar threads links at the bottom there have been many old threads being revived often for no apparent reason. For example today I saw this thread from 2003 pop up with new posts. And as in that thread the reviving posts are usually not related to the subject of the thread or if they are related it is usually because someone feels the need to correct information that may have been correct at the time but due to changes in hardware or the OS is no longer correct. So I was wondering if it would be possible to automatically lock old threads after they haven't had any activity for a certain amount of time, I'm thinking about a year. If they are locked people can still see the information if it is relevant to them but it would keep old threads from popping back up with irrelevant content.
