How to Add A Spoiler Section To A Post

[tmorrow]

Browsing around diablo.incgamers.com/forums I've found that some people have a spoiler button in their posts (usually trade posts) that when clicked will show the spoiler. How is this done? I've looked at the options in the "Post New Thread" window when creating a post and I can't find the option.

Use {spoiler}add your text{/spoiler}.

But use [ and ] not { and }.

EG
add your text

Awesome, I just tried it out in the post editor and it works perfectly. Thanks Thyiad!

To find out how "tricks" like this are done, just quote the post (as if you wanted to reply to it) and you can examine their code.

That quote post trick is very useful, thanks Oscuro.
