There have been requests for this and there are a whole lot of black spoiler bars in the open thread that could be accidentally moused over, thus ruining someone's life. So let's talk all Game of Thrones stuff here. Here are the rules:
1. You are free to talk about anything that has happened on the television show that has already aired. If you for some reason have knowledge of something that will happen on the show (as in, you discovered it will be on the show, not it's a plot point in the books), use the spoiler bar and note that it's for an upcoming episode.
2. If you want to talk about what has happened in the books, it MUST be under the spoiler bars and it must contain the words "book spoilers" somewhere in the title of the comment.
That's it! Now have at it.
