block

In Drupal 5.x with the Views module we can easily create content listing blocks. There is an option for switching on the "more" link on the Views edit page. If you would like to change the word "more" to something else, you can add the following code to your template.php in the theme folder:

/**
 * Override the more link on view block
 */
function phptemplate_views_more($url){
   return "" . l(t('[Read more]'), $url) . "";
}

Don't forget, that this function will override every "more" link on every block.
If you would like to theme only one "more" link, you have to come up with a better idea. Sorry :)
