What is Wrong With My Signature?

[maounkhan]

I see many people using a spoiler. Click on it and woah, more information comes up. How do we make this, give it a title, put information in it? I am thinking of using spoiler in my signatures.

Edit: There is something wrong with my signature. What is it?

[spoiler=title]ehhejjsjs[/spoiler]

Just like this:

[Spoiler=Not a spoiler]Hi![/spoiler]

Will turn into this:

Spoiler: Not a spoiler

Hi!

 

[maounkhan]

OK, thanks
