I can't find a way to edit my signature,  at the bottom of each post.  I forgot how I recorded my signature (see below: "Tax junk foods"  Anyone know how to edit that?

Go to your page by clicking on your name, and at the right toward the top there's an Edit Profile button. Push that and your signature should be at the bottom of that page.
