There are now links at the bottom of the page for “Previous/Next Page.”  This should be working for the Archives and Categories pages as well.

Note that you will not be able to comment on posts that are more than 21 days old, it was the most effective way to stop the absolute flood of comment spam that needed moderating.  Keep in mind for your own websites that the spam-bots typically target old posts.  All they are trying to do is get their links in your posts so that google will read them and rank their pages higher.
