I've been off the grid and catching up. <br><br>We have a variety of tutorials on the Codex that are outside of "official documentation," whatever that means. In the past, that meant anything in the Codex that passed the muster of the docs team (or any passer by. :D ). It became representative of documentation that was "frozen," linked to from the WordPress Administration Panels. <br>
<br>There is no reason why a tutorial article on such a task would be allowed in the Codex unless the rules have changed. If this is an example usage of an existing filter, then it would be an excellent addition to the Codex. <br>
<br>From my two cents worth of input. :D <br><br>Thanks,<br><br>Lorelle<br>
