Okay, now I may be going crazy, or just missing it somewhere. But I've browsed through all of the options I see available when I'm posting in a tread but I can't seem to fin the option or feature that I see all over where it says spoiler and once clicked the post expands to show hidden information. If I'm really so oblivious I'm missing something totally obvious, I'm sorry.

Nevermind! I just found the tread in this section retaining to this. Sorry mods!
