Purge allows you to permanently delete user activity data, including Ask an Expert and Feedback threads, as of a specified date. This also removes the data from the reports; some reports may show different cumulative data after the purge. Completion data is preserved; the purge process creates a rollup record that keeps the best score and the most recent completion data.
Note: Users with Expert or Feedback Monitor permissions for specific titles can delete (purge) individual conversations for those titles using the View Report link from the Review Feedback or Answer a Question pages. From the report, they can use the Delete Conversation link to permanently remove an entire conversation from the server.
