Kind of confused. I once was able to start a discussion, and your "Rules of the Road" tell me I can do that, and that I am to see a green rectangle button with the words "start a discussion". BUT the problem is, the button is no where to be found. Where is is? I signed out, logged back in, scrolled to the bottom of the screen, went to the top, clicked on the three little dots, checked under My Profile and found nothing.
