Okay I think its fixed. Click on your avatar in the upper right corner. It should bring up a black box with a link to your profile page. Click on profile page, click on screen name in the upper right corner of this page. You should have a signature option there now.
Bordertangoman-Please try these instructions (see quoted text) for finding your signature. I have set permissions for your username. So signature option should be there. However, please let me know if it is not.
