The Moodle Messages feature will be turned off as of August 23, 2012. If you have exchanged messages that you would like to preserve, you can retrieve them. For instructions, please see: http://www.oit.umass.edu/support/moodle/retrieve-messages-moodle
Note: Discontinuation of the Messages feature in Moodle will not affect email notifications from Moodle or Quickmail in Moodle.
From time to time, we add features to Moodle, but it is unusual for us to remove features. More about the Messaging feature and why we are turning it off.
