I'd like a sidebar widget that lists the posts OLDER than the one being viewed.
So, if the user is reading the oldest post, there would be nothing listed.
If they're reading the 2nd oldest, the sidebar list would show the oldest.
If they're reading the 3rd oldest, the sidebar list would include both the 2nd and 1st posts, etc.
I've searched but can't find anything that does this. Any clues, help, solutions?
Thanks in advance.
