You're of course free to discuss those kinds of things here, we only ask that you be cool and keep overt spoilers out of thread subject lines. We'll be heavy handed on those who are overtly attempting to spoil things for others.
That said, if you're worried about spoilers you should exercise caution when visiting World of Warcraft related forums and websites anywhere as well as in-game chat.
