If you're talking about the widget on the home page, I changed the New Posts widget to differentiate between new forum posts and new classifieds. There are two tabs at the top of the widget - new forum posts, and new classifieds listings. Your post shows up in the new classifieds listings.
If you're talking about the sub link under the Forums menu (that pulls up all the new posts), I see your new post there.
Ah. If I look a little closer, I don't appear to see any of my own content in the New Posts overview. So it looks like it avoids showing you things you've actually posted (which makes sense - that's not a new post for you).
I do see your Classifieds thread, though, and have verified that normal (non-mod) registered users see it as well.
