+
+## Norms for virtual class
+- Mute yourself when you are not talking
+- Recommended (not required): turn on your video
+- Use the chat for questions/side discussions
+
+> If you wouldn't do something in a real classroom, you probably shouldn't do it
+> in a virtual classroom.
+
+## Guidelines for discussion
+- Basically: **be nice to one another**
+- WAIT: Why Am I Talking?
+- One mic: one person speaks at a time
+
+## Accommodations for remote students
+- Strongly recommended to attend live lectures
+- If you can't (e.g., lecture in the middle of the night):
+    - All lectures will be recorded on BBCU: watch them
+    - Do **two paper reviews per week** instead of presentation+summary
+
+> Let me know ASAP if you are remote so I can set you up with paper reviews
+
