Format for pinging with @

[The Options Menu]

I was just curious about the correct way to ping a user with @, in a post, when they have multi word names.

Is it:
@"The Options Menu"

Or can I omit the quotes? (Or is it something else?)

@The Options Menu

Like that.
When you type @ it will automatically popup.

Thank you @Shaquille Oatmeal

I didn't want to bug someone by randomly testing, and yes it did pop up.
