Currently students can either:
1. create a public link and share that on a discussion
2. share their video with individual people via the People interface
If they choose option 1, the other students in the class cannot directly comment on the video.
If they choose option 2, they have to manually type in the name/email of every student in the class.
If there was a way to share their videos with the entire class, so every student could comment on the videos that would be fantastic.
