how do you hide text?

[Tchos]

Several months later I can say I just found this to be an issue, when someone posted a spoiler for one of my quests in the file comments. I asked him to use a spoiler tag, and I found that the spoiler does just as you said, Thandal -- in the forums hides it nicely, and in the file comments leaves it the same colour as everything else and underlines it for emphasis.
