We have added the spoiler alert plugin to the server to bring back spoiler tags. To use this encase your comment in the following tags:
[spoiler][/spoiler]
It will look like this:
A spoiler is an element of a disseminated summary or description of any piece of fiction that reveals any plot elements which threaten to give away important details. Typically, the details of the conclusion of the plot, including the climax and ending, are especially regarded as spoiler material. It can also be used to refer to any piece of information regarding any part of a given media that a potential consumer would not want to know beforehand. Because enjoyment of fiction depends a great deal upon the suspense of revealing plot details through standard narrative progression, the prior revelation of how things will turn out can “spoil” the enjoyment that some consumers of the narrative would otherwise have experienced. Spoilers can be found in message boards, articles, reviews, commercials, and movie trailers
You can then click the text to revel and hide the block.
I hope this proves useful.
