Well! After about an hour I was beginning to feel like I was excluded in this all inclusive organization. I got to this posting place by luck, depending what you believe in. The "Go to the discussion" link in my gmail on my MacBook Air, sent me elsewhere. Once I signed in on my cell phone, both the the wall link on my cell and my computer worked.
I'm going to wait for another day to try posting again! (Hopefully this glitch is fixed now and if not, there's the temporary fix, above).
