Yes. I can use phpmyadmin.
I guess what I need to know is how to completely delete a post. In phpmyadmin when I go to the table wp_posts and then browse, sort by id, and find the post that I think is giving me trouble (68), it says this when I click the check box, then try to delete:
SQL query:
DELETE FROM wp_posts
WHERE ID
=68 LIMIT 1
