If you're in a movie thread etc and want to post a spoiler comment we have a lil feature that will allow you to hide the comment. A viewer must click the + spoiler tag to read, thereby not being able to accidentally read it.
(spoiler) type your spoiler here (/spoiler) --- use square brackets insted to make this function.
It will appear like this
and after you've closed the tag [/ you can continue with the rest of your non spoilery post!
