We’ve just launched support for comments, where users and admins are able to add comments to questions and/or comments.

To enable comments for your site, simply go into your administration area and click into the “System Settings” area.  Under the System Settings area, click into the “Feature Preferences” option.  At the bottom, you’ll see two new options for adding comments to questions and/or answers.

Enabling comments for questions or answers will give you the ability to have users clarify their information, to help provide more effective communication.  These features are optional, and only encouraged if you feel it will work well for your audience based on your market and your experience with how they communicate.
