 Two blocks which are useful for us as a teacher to keep in touch with our learners and our co-teachers are the online users block seen on the left here and the messages block. As with other blocks, to add these we need to turn the editing on either by clicking the button top right or by clicking the link in the administration block. The online users block shows us who's been recently online and who is currently online now. This is useful also in a face-to-face teaching situation if you're in a room and you want to make sure that all of your learners are currently on the same course page as you. The messages block is a quick way of seeing who has sent you any messages and you can read them by clicking them here. Similarly you can use the messages block to locate learners who you wish to message and send them a message.
