* - replies to nodes

* - attempts to reply to nodes that can no longer accept comments
|

* - respecting access permissions ('access comments', 'post comments', etc.)

*
|
| 17 |
* The node or comment that is being replied to must appear above the comment

* form to provide the user context while authoring the comment.
