I would like to add another signature to my account...

I have been trying to follow these instructions: https://helpx.adobe.com/sign/using/create-electronic-signature.html But I just dont see where I can add a signature to my account.

I have 2 already saved (mine and my business partner) in my account so I can drag/drop them into documents when we need to sign something on the fly.  I would now like to add my wife's name to the list. 

I am getting off track when the directions tell me to navigate to the "create" section and then type or sign the name ... any help appreciated
