Settings: Discussion (Used to be Settings > Discussion)
This screen has some new settings for comment threading and pagination, in the second group of items labeled “Other Comment Settings.” Use the checkboxes and drop-down menus to enable comment threading and/or pagination if you wish. Note: not all themes have been updated to support comment threading or paging, so these options are turned off by default.
Love the new Dashboard. WordPress, WELL DONE! So i take it that The Journalist doesn't support Comment Threading or (CT) has it not been implemented yet?
