OK, this may be a newbie thing. But just in case anyone else has the same issue.
I was not able to see any charts, pictures, vids in the forum.
All I could see was the text.
Posts would say they attached this-that or the-other, but I could not see it.
I tried both Firefox and Internet explorer
I tried http and https
Nothing worked, until I logged in to the forum with a login and password to post something.
And then I saw all kinds of things.
So at least for me, one has to login to the site to see more than just the text posts.
