:snicker: Just as I'm about to type that the forum has to be set as a news forum to see the news images; I look down and see you figured it out, lol.
But yes, as you've observed it is not a forum icon, it's ultimately just an icon for the portal page; an option that, if the system was created today, probably wouldn't be there.
I kinda like it, now that I know how to use it
