Topic display pages show the responses in a topic - either all of them or just a range. A sample:
newstech.4: Wish List for New Features
In addition to the standard buttons, topic pages may have an [Earlier Responses] button at the top and/or a [Later Responses] button at the bottom. If the topic page isn't showing the entire topic, then these buttons appear to show previous or subsequent responses. There are also some topic-specific commands at the bottom: [Forget], [Retire], and links to the topic as a whole and to the conference.
Lastly, at the very end is a form for posting a new response to the topic. Just fill in the text, and optionally a pseudonym for just this response, and hit [Post].
