Can someone explain this to me? Whenever someone posts in a thread where the 2nd to last comment is more than 14 days or so away from the last comment, people usually say revive. Then, at the top, it says that the thread is closed by someone like people named Zedkiller, Yami Riku, or whoever else. Can someone explain to me this process?
