I too have a very difficult time getting students to attend the chat sessions. I have tried emailing, posting announcements, etc. to remind them, but nothing seems to work. I did try texting for one term, but one student complained to my supervisor that I was "overbearing" and bugging him on his cellphone (I texted the entire class once per week). She asked me not to use the students phone numbers unless I was contacting them about attendance issues. I know that most students don't listen to the recording either. I would discuss specific clues to passing the class and doing well on the homework assignments in the chat and no one followed the directions. It can be very frustrating.
