During online office hours I will be on Zoom for video conferencing.
The Meeting ID will be posted ahead of time on Canvas.

(Most likely Canvas sends out automatic announcements as well.)
Besides, there are Canvas discussion groups for questions on topics like
homework, exams, lecture notes, and organizational questions.
