A quickie here. I've hardly ever had to use this function, so how do you isolate text as "Spoiler" during posts?

In the post box, top left corner, 3rd on the right. "Special BBCode".

or just [ spoiler]"Text to be spoilered"[ /spoiler], sans spaces inside the square brackets.

Thanks both. I was looking all over the place for something obvious. No wonder I couldn't find it!
