Daniel Gruno has recently developed a comments system for Apache projects to use. The purpose of the system is to enable public commentary on project webpages and is already in production use in the httpd and trafficserver projects. This new system nicely complements the ASF CMS system and trivially integrates with it- see http://comments.apache.org/help.html for details.
The comment system is now open- enjoy! Please file a jira ticket with INFRA to get started today.
