Site Audit module backported to Drupal 7 to soften landing of Drupal 7 upgraders.
After my presentation on Site Audit 4, I was approached by an audience member, Irina Zaks of Fibonacci Web Studio.
It turns out, the Site Audit module never had a web interface in Drupal 7. It was a drush-only tool that could output HTML, but there was no code ever written to display the audit in the site.
