Just wondering, do created threads stay in the archives forever? or is there a time limit before they get deleted?
As far as I know they remain forever unless someone deletes them. Apart from closed/moved/duplicated threads, we've never had a clear out of old threads, so the archive should be pretty complete. Saying that, however, the forum has changed server a few times in its history and moving databases over has sometimes created problems. For instance, when Taz changed server about five years ago, all of the opening posts from each thread were lost and the Council had to go back to the old server to retrieve each one manually. If you look back at some of those old threads, you'll still find some with missing opening posts, or ones where the whole thread has posts that are out of order.
