Once upon a time, there were two threads. One was a thread for discussion of the HBO series Game of Thrones. The other was a thread for the book series A Song of Ice and Fire.
They existed together in a constant state of war, and yea there was much strife and reporting of people who would dare to talk about the books on the show thread and vice versa. And verily was this really goddamn stupid and irritating.
Then one day, the all powerful Mod realized that other subforums managed to make do with a single thread for both those things, and even D&D's own The Walking Dead thread could handle book and show discussion in one thread without collapsing into stupid.
And so it came to be that the two threads were struck down and replaced by the One True Thread, a place where all could exist in harmony, secure in the knowledge that the enemies of good etiquette would be exiled for all time.
Short version: you guys get one thread. Don't be dickholes about it, and it'll work fine. Use spoiler tags to indicate if something has only happened in the show or only in the books, within reason. If someone is being an asshole, report it. Use common sense.
You can do this! Don't get shown up by those dumb fuckers in the Walking Dead thread!
Edit: Also! Helpful guideline regarding book spoilers:
The following book related topics should be in spoiler tags:
BOOK PEOPLE ONLY CLICK THIS SPOILER
-Everything Greyjoy from Balon dying on.
-Anything having to do with the BwB, or Lady Stoneheart
-Anything having to do with the Citadel
-Anything having to do with the North Remembering (and the northern lords rebelling against the Boltons)
-Arya warging (and Nymeria/visions/etc)
