I was having a continuous conversation with a classmate during the final weeks of our class, discussing our majors and future career decisions, etc... It was an important conversation for the both of us. The class ended and now I am unable to respond to their last message. I'm uncertain about how to respond to them if the class is now locked or closed? I only know them in a professional and academic manor and do not have their email or another form of contact, is there a way to continue messaging them through canvas?
