You can post comments to any case. Comments can be either public (viewed by anyone) or private (viewable by only the comment author). Comments are useful for leaving searchable notes to yourself about a case, leaving feedback for the case author, starting a general discussion, pointing out additional findings, or questioning the validity of the case.

The owner of a case will receive an email every time a comment is posted to his case.

To post a comment:

1. Be sure that you are logged in and Training Mode is turned off.
2. Click on "post a comment" which appears near the end of the case, above "Additional Details":

   

3. The comment form appears, allowing you to enter text and select Public or Private. If you choose Public, all users visiting the case will see your comment.

   

4. Click "Submit Comment". The comment is now attached to the case:

   

The author of the case will receive an email alert that a comment has been posted to one of his or her cases:

Be judicious about the public comments that you post: you are leaving a record on someone's case, and the author of the case cannot delete your comment.

You can edit or delete your own comment by revisiting the case and clicking on the corresponding link to the right of the comment.

You can retrieve cases by searching for comment text. Go to Advanced Search, enter the search text, and uncheck all the "Match On" boxes except for "Comments:"
