I appreciate the definition of hijacking a thread.

I know I have been guilty of doing it. At least once, I responded to one person within the thread. Then that person responded back to me. We were both online at the time and we ended up posting back and forth within the same thread, within an hour. We should of taken it to PMs or to a chatroom. At the time, it was quite innocent. I don't plan on doing it again . . . but, it can happen easily. I have seen many threads hijacked. I'll keep this "hijacking" definition in my mind each time I respond to a post. Thanks!
