One of my joys in life as a Moodle site administrator is scouring the Net to unearth gems of Moodle activity modules of earlier years. Such is the case with Mediabird Study Notes, which allows you to add private and community note-taking to your Moodle site! Never heard of it Mediabird Study Notes? This blast-from-the-past (April 2009) is a real gem of an activity module for note-taking.
Private Notes
With Mediabird Study Notes you can have your own personal note-taking database system. This virtual notebook is available to you wherever you go in your Moodle course.
Sharing Your Notes
You can also share your notes with others who use your Moodle site. Share them with any specified group of people that you choose. You can even be an admin of the group that you create in Mediabird Study Notes. As admin you get to share your notes with, you control who gets access.
