Spoiler Tags

I've far surpassed the amount of information contained on this wikia by now, so spoilers do not affect me, but I think it would be in the best interest of the community and the fandom to create a spoiler alert system, considering how many plot twists are contained in the books. Just reading what is currently on the Illuminae page would result in spoilers, which (while it may be expected) should be marked all the same.

tl;dr: can we get a spoiler tag working?
