To necro a thread is to post on it long after the thread has lived its life. Suppose the thread had its last post some time in April or May of this year, it's dead. If somebody digs back and finds it, then posts to it, they revive the thread. This revival is called a thread necro. I personally do not like thread necros because they are confusing. In some forums, thread necro is against the rules. I am wondering what the stance of this board is. I tend to report posts that necro threads, but I will stop if this board is okay with it. -xmarkd400x Edit: The general rule, if you wish to comment on a dead thread, is to create a new thread and link to or quote from the old one.
