Auto node body!

Hm, it's possible but I not plan to implement this. Doesn't seem to be required often either.

I don't plan to add this to the module.

Try out http://drupal.org/project/reptag and if it doesn't support tokens, ask them to add token support

I read through some log messages (searched for "token") and it seems the module reptag has token support.

Let me know if it solves your problems.

A solution can be achieved with http://drupal.org/project/computed_field
but it needs a little custom coding

I have not done it
but I know it can be done

look for snippets/example code here
http://drupal.org/node/149228

Here is what I use to get a 10 word title:

<?php
$limit = 10;
$text = $node->body;
$text = strip_tags($text);
      $words = str_word_count($text, 2);
      $pos = array_keys($words);
      if (count($words) > $limit) {
          $text = substr( $text, 0, $pos[$limit]);
          $text = trim( $text );
          $text = rtrim( $text, '.' );
          $text = trim( $text ) . '...';
      }
return  $text;
?>

Works for me in Drupal 6.20.
