Ohhhh....! Ok! The problem was, I had my preferences set to Basic Editor. You have to reset it to the most advanced version, in order to get the little paperclip to even show up. Even if you go into Advanced Editing-and you're still in basic editor-it won't show up.
I feel a lot less stupid now, and can simply focus my ire on the new forum setup, where it properly belongs
Thanks again, Ich! I just wasn't seeing what you were seeing, and by showing me that, I finally figured it out.
