There's been some upset lately regarding spoilers particularly regarding Game of Thrones. A simple rule of thumb - if in doubt spoiler it. If it's not been broadcast use the Spoiler SPOILER tag. The topic title will normally advise if spoilers are included. Obviously talking about season 1 when season 5 is on should be fair game - common sense prevails. Carefully identify Youtube clips if it contains a spoiler. If we all stick to it, then we won't ruin TV for everyone else.
