How to override the "formatting tips" section in Drupal's node creation

Drupal provides some "formatting tips" just before the submit button when creating nodes.

Sometimes you want to override this text to provide your own "tips" for node creation. Here's how to do this :

In your theme's template.php file, add the following function :

function phptemplate_filter_tips($tips, $long = FALSE, $extra = '') {
return 'Your tips here';
