+Q: What happened to the Mollom Content Moderation Platform?
+
+A: On Thursday, 1 October 2015, Acquia is ending support for the Content
+   Moderation Platform (CMP) feature of Mollom, which was originally added as a
+   feature in 2013.  Users who activated their CMP accounts before June 1, 2015
+   will have access until that time.
