The Announcements forum is a special forum that is automatically included in most new site requests.
It is set up so that:
Only the instructor can post – students cannot post topics or reply.
The subscription mode for this forum is Forced Subscription.
Students receive an email when the instructor posts even if the course site is not open.
Since the Announcements forum can be deleted, this article shows how add it back into your Moodle site.
Adding the Announcements forum back into your course site
Go to the course homepage and click Turn editing on.
Look for Add a Block at the bottom of the left column.
From the Add... menu, select Latest News. The page will reload. The Latest News block AND the Announcements forum are added to your course site. You can find the Announcements forum in the top summary topic area in your Moodle site.
Remove the Latest News block if desired.
Click the Action gear in the upper right of the block, then select Delete Latest News Block.
Confirm your choice. The Latest News block will be removed from your site, but the Announcements forum (News Forum in 2.8) will remain.
