A little known change to Moodle was highlighted last week during the General Developer Meeting where the new messaging process was highlighted. Messaging now no longer requires you to load your own messaging page to see the back and forth between you and the recipient.
Instead, wherever you see a user’s name in places such as viewing their profile, or looking at a list of online users you can click a little message icon to initiate a messaging popup without leaving the page. If you’re interested in trying it out go to http://qa.moodle.net or check out the quick higher res gif below.
