now, if you go into edit profile, and click on signatures, you will be able to add an extra signature, and then, if you go back in there, you can add another, and then another. Then, when you make a post, there will be a drop down menu at the bottom and you can select which signature you would like to display. I now have five of them. The first one you make is the default signature that will show up if you do not select one.
