I have taken part in some chat between the teacher and the student. The blurb says that new items will be in red and older ones in green. I logged out, added a new message from the student then logged back in but all comments appear to be the same colour. Not important but I’m not sure if I am interpreting things correctly.
Andy, sorry this text is our of date. The other members of the class now receive a notification when there are messages, so the colouring was removed. I have fixed this in the most recent commit to the v11 dev branch.
