[support] access content summary option not available

Hi All,

I'm following the this (http://drupal.org/node/408018) tutorial to creating categorized content and at the end of item 6 it says "Finally, under the module_grants section tick “access content summary” for authenticated users. Press “Save permissions”." But under User management>>Permissions>>module_grants module I see only the followings access 'All' tab access 'I can edit' tab access 'I can view' tab access 'I created' tab access 'I last modified' tab access 'Published' tab access 'Unpublished' tab

I don't see the 'access content summary' option. Am I missing something here or has this option been renamed to something else? I'm on drupal 6.13

Thanks, Dhanushka.
