The pinned forum post should not be pinned in the forum summary gadget.
We're just starting out, but the one forum that has a pinned post is showing that pinned post as the first entry on the forum summary gadget. It shouldn't be pinned there at all. If I limit that gadget to 5 entries and there are 5 pinned posts, that gadget will never update since it'll always be showing the pinned posts.
At this point, I'll need to exclude the one forum using the pinned forum post. -OR- I'll need to unpin the post and add it as a notice above the forum gadget. Neither option is ideal.
