This discussion may contain spoilers!
Post something spoilery, but not really that spoilery, because everyone already knows about it! You can give a dramatic intro, such as "Oh my god, I forgot to tell you..." or something like that, and you can comment on others' false spoiler.
Don't post anything mean about other people, and don't post any real spoilers. It's gotta be something everyone knows about.
Light is Kira.
