By default, all courses in St. Norbert Moodle have an "Announcements" forum.
There are a few useful things about this forum.
1. All students are automatically "Subscribed" to this forum, so they'll receive emails whenever you add an update to it.
2. The content of a forum post can be many things. You can use it to post a video, link external content, provide a set of expectations, and much more.
3. It has all of the attributes of a forum, so students can publicly reply to your updates.
To create a forum post, click on "Announcements" in the course.
Click "Add a new topic"
Then, you get to create an announcement. You can customize font size and style, link external content, or place images, videos, and other attachments in-line in your announcement.
Once you're done adding your content, click "Post to forum", near the bottom of the window.
