If you’re using blog posts in a class, you may need to show an “audit trail” for the blog posts to indicate that it was posted before a deadline, and not edited afterward (because, you know you can always edit the “Published On” date for a post… not that anyone would do that… *cough* )
So, I whipped up a quick plugin for WordPress that, when activated, will automatically display the audit trail beneath each post on the blog, like this:
To enable the plugin for your blog, go to the Dashboard, and click the “Plugins” link on the right side near the top. Find the plugin “Post Revision Display” and click the “Activate” link for that plugin. That’s it. There is no step 3.
