If you want to receive quick updates of any changes, like a last-minute class cancelation, or you want a mechanism for “texting” the class or just the professor, I have set up a GroupMe that you can join so that you receive updates by phone. Once you have GroupMe installed, you should be able to join our group with the following invitation link.
Once you’re in the group, you can then send individual “texts” to others who are in the group, Dr. Banks included.
