I am using the Chateau theme. When someone leaves a comment I go in and approve it and then hit Reply. But my answer looks like a new comment, rather than indenting to the original comment, so you don’t know who I am responding to. Do I need to set something up? If so, I can’t figure out where?
That is called comment threading or comment nesting. It’s not enabled by default so you must have selected it. You can disable it on this page > Settings > Discussion
4. Enable threaded (nested) comments __ levels deep- Turn on this option to allow visitors to reply to other comments inline/nested. When turned on it can allow for better discussions and responses. We suggest using a maximum of 3 levels deep. Anything higher and the theme layouts may not work as expected. Note: Enabling the setting only applies to new comments since existing comments don’t have any threading date. However, disabling this setting applies to all comments. http://en.support.wordpress.com/settings/discussion-settings/#other-comment-settings
