Your title should convey what the thread is about. If you really want post from people who play "Knight Online", you need to indicate that you're talking about that game from either the forum the thread is in, or the thread's title. Just naming the thread "anyone play this mmorpg?" is setting yourself up for a lot of "no, I don't" posts by bored people obsessed with their post count. Many people don't bother to read a thread if they can't tell what it's about from the title.
