Installation Instructions

1. Download the plugin archive and expand it (you've likely already done this).
2. Upload the old-post-alert.php file to your wp-content/plugins directory (not in a sub-folder).
3. Go to the Plugins page in your WordPress Administration area and click 'Activate' for Old Post Alert.
4. Congratulations, you've just installed Old Post Alert.
5. Optional: set a CSS class for old_post_alert to style the banner.

FAQ

Why doesn't the banner show in my theme?

This plugin relies on the comment_form to be present in your comments.php template. If this does not exist, you will want to add it:

<?php do_action('comment_form', $post->ID); ?>

Anything else?

That about does it - enjoy!
