Most posters in this section are pretty good at this, so this thread is aimed at others. Since this is a section dealing with books, obviously with plotlines, it is similar to the sections on the upcoming Prequels. Not everyone wants to know plot details before they themselves see/read them. If you are mentioning any plot detail, put a "Spoilers" note some where easily seen (preferrably in the title, for new thread creators). A "spolier," in case you haven't heard, is information that could "spoil" the surprise for someone yet to experience the story.
That's all. Not a complaint, just to inform.
Your friendly neighborhood Bel-Cam Man.

Where ever there's a hang up
You'll find a Bel-Cam Man!" )
