Informative posts worth sharing with the viewers of the board. Each mod can sticky one post. That post remains in the yellow above until the mod exchanges it for another post.
Pretty sure he is referring to the section just above the last post, that doesn't go away. They stay there, like a sticky note, for everyone to read. It's tinted yellow (like a sticky note) and has a little "sticky note" icon on the left side of the post. I believe only admins can sticky a post.
