How do you make a Permanent Sign Off???????

I would like to have permanent quote each time I post but I cannot seem to locate on my Edit/Profile page how to do so.

 

Would someone be so kind as to instruct me how to do so without me having to re-type it each post.

 

Thanks!!

Thanks HeadOverHeart. I didn't see the Covers Help Forum. It was below my screen and I didn't scroll down  enough. Will do.

 

As for what I want to always be my sign-off it's the following quote:

 

Gambling promises the poor what property performs for the rich, something for nothing." George Bernard Shaw (1856-1950) Irish writer.

 

I belong to another discussion forum and it allows us to permanently set our avatar and have quotes/sayings at the end of each post. It is just like having your name and title at the end of your Outlook e-mails at work without having to always type it.
