My suggestion is that it could be useful to clarify the policy on replying to older threads. I know this has been discussed in the past, but I have not found any recent discussions. As a newer member I find this issue a bit confusing. My impression was that if a thread is not locked, it is fair game for a reply. Some threads may be a bit older, but still useful. Would it be technically possible and/or advisable to automatically lock an older thread to which there has been no reply within a given time period? Then we could assume that any unlocked thread is fair game. Thanks.
