Did that first off, just shows the link and not the actual post. Have done it since like this post https://investorshub.advfn.com/boards/read_msg.aspx?message_id=175289137 where I just copied the text and put the link. It's not showing the post view like yours, just the text I pasted with it.
Nor does this one, at least in the preview, maybe when I post it. Am I doing something wrong?
