How do I disable the "Group activity" tab on the organic groups page I've got organic groups setup in Drupal 6 and have been asked to remove the "Group activity" tab from the groups page (example.com/og). I suspect that this is being driven by one of the views, but I can't seem to find one that is powering it. Is it possible to disable this tab or control its output at least?

This tab appears to have been removed from the Drupal Groups site: http://groups.drupal.org/og
The Tab tamer module is a quick and easy way to hide or disable extra tabs.
