I experimented with the Mindmap activity after reading about it on Moodle.org

It is so easy to use, and I think it would be much easier for students to use this to create a mindmap then what we currently ask students to do (either do it by hand or using a word processor). This way they won't have to open up another program or use the scanner if doing it by hand, to complete the task. I created by own in less than a couple of minutes.
