How to use spoiler options?

I'm new at this, so how do you add the blue box that says "spoiler:"?
Also,how do you delete threads?

 

First
[ spoiler ] spoiler goes here [/ spoiler ]
Delete the spaces


Second
Report your own thread and request it to be locked, it won't be deleted unless it's something severe, I guess.

Spoiler

Like this

Click on the plus and then spoiler good luck have fun

 

two ways, one, like @R0 pointed above,


you can even put a title into the box, like this,


OR, the second way, like @L4 pointed out, which involves less typing but more clicking,

 

Typing is harder =3= clicking is 2 clicks matey

 

Only once? For me it's once on the plus then on spoiler and then on okay

 

Zoom in, first?
