Well, I feel they can start a new thread. Some thread are old news that don't even apply to us anymore (think about reviving a thread about which "pager" to buy when it hardly exist anymore). Second, some people are replying to the posters who no longer around so the questions get left unanswered. Third, It's confusing as we think it is a new post. One time, someone revived a post that had one of old member, and I thought he came back and was happy about that... then later, I was disappointed it was just an old post.
