plone.app.discussion replaces the old commenting system in Plone 4.1 and is also available as an add-on product for Plone 3 and 4. It was initially developed as part of the Google Summer of Code 2009 by Timo Stollenwerk (student) and Martin Aspeli (mentor).

Please report bugs to the Plone bug tracker.

For the roadmap of the project see our Pivotal Tracker.
