So here’s a tidbit for anyone adding the Activities Stream widget to a custom page. While the documentation in the KB states: 

“This widget shows the user’s new enrollments into courses, and assets, Q&As and comments that have been published in the platform.”

It actually does not include any comments made to assets or via the course comments or forum widgets. I filed it as an issue with Support but apparently it’s the documentation that’s wrong. We would love to have this widget show all activity including any comments on assets/courses. There’s a suggestion in the Ideas Portal LMS-I-3004 if anyone else would find this change helpful.
