Hi Ellen, @ellenn, also in additon to what @poodledoc has advised you, on Page 1 about the middle of the page on the right-hand side you will see a small box where you can select either 'Oldest to Newest' or 'Newest to Oldest'. 'Oldest to Newest' is the default so you always start on Page 1. Select 'Newest to Oldest' to go to the most recent posts.
Good luck
