Installation instructions (see also http://www.ilfilosofo.com/blog/comments-preview/ )

1. Upload the filosofo-comments-preview.php file into your plugins folder (in http://www.%your_blog_address%/wp-content/plugins/) and activate it in your control panel.

2. If your WordPress version is 1.5.1.1 or newer, or if you're using only popup comments with 1.5, then you're done!
 (You can find your WordPress version at the bottom of the admin pages for the blog, after logging in to the blog.)
 
Otherwise (e.g. if it's version 1.5), see the plugin page above for instructions.
