Overview

Comments can be added on a per discussion basis. There can be replies to other comments in the same discussion. Comments are signed by the user commenting. Public comments belong to the user anon (see #User) and must have the ‘athor_name’ field set.

If anonymous is moderated (User#moderated?), all public comments are set to ‘prop’ and are not directly seen on the site.
