Hi joanie1! Page 1 currently shows posts 24-73 (or thereabouts)...
(If someone posts a new post after I write this, it might change by one, or two.)
Page 2 shows posts 1-23.
To see page 2, at the top and bottom of the page it says "Page 1 2". The 2 is clickable. Click on it, and it will take you to page 2.
Page 1 will always be the most recent page, and page 2, 3, 4, 5, etc. will be the older pages, with page 5 being the oldest page (for example).
We can't change that because down the line we would be on Page 43,234 and it will invite us to click on 43233, 43,232 and 43,231. That would be too weird.
Oh dear, now I'm up to 100 posts.
