Introduction

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).

Note

Make sure you pin down plone.app.discussion to versions < 2.0 if you want to install it as an add-on product (see install instructions below for more details).

Please report bugs to the Plone bug tracker.

For the roadmap of the project see our Pivotal Tracker.
