In a Ikiwiki instance, I made a subdirectory to hold blog pages

/website
blog.mdwn
...

/website/blog
/website/blog/blog1.mdwn
/website/blog/blog2.mdwn
...

On blog.mdwn, reader by default see the last 10 posts, but it seems there is no link to blog pages older than that. What's a good way to make titles of blog pages older also somehow visible to reader at the blog front page blog.mdwn?

On any individual blog page such as blog1.mdwn, there is not a link to the blog pages immediately before and after it. How to make such links?
