Agree with kbenker, adding post_date is a better move for several reasons, not the least of which is the query could otherwise pick up future dated posts.
If you’d like to further limit the plugin to show only a set number of posts, add this:
AND wposts.post_date < NOW()
ORDER BY wposts.post_date DESC
LIMIT 0,5″;
That will put your posts in order by most recent first, and limit the display to the most recent 5. If you want more posts, just change the number five to whatever number you would like to show.
If you want the oldest posts (not sure why you would, but hey…) then change the DESC to ASC and it will grab the five oldest posts.
