This hack offers two ways to moderate comments. First, and easiest, is to require registration before someone can leave a comment. Second, and more complex, is to make the comment be a 'draft' until the post author publishes it. I tested both methods, but not as completely as I like to. If you use it and run into a snag post your problem in the forums and hopefully we can work it out.

This hack adds a button to the backoffice editing page that lets you display code in a blog post.
This hack counts how many times an article has been read. This is a high performance solution which works quite well. Read forum topic for the implementation.
What this does: it redirects the client (and no server redirect!) to a new URL. Because I renamed my index.php to goedzo.php, this works for the real user. The spammers will never follow this redirect.
