 Okay, so we're coming into a course. The first thing we're going to want to do is turn editing on, go to the topic concerned, add an activity. Let's choose a forum. We'll give the forum a name and an introduction. Now down at the bottom we will have common module settings. So if we've created groups, we want to select group mode. We've got two options here, separate or visible groups. So in this case, let's select separate groups, save and display. Now this remembering is all done through the eyes of an admin or an editing teacher. So there was just the advanced settings that I must have got there. So that's good. No worries. So we've got all participants and then we toggle to a given group and then we can post a topic for that particular group. So any members of this group will see this post and again we can attach a file if that's relevant as well.
