The Announcements forum is a special forum for general news and announcements. A course may only have one Announcements forum unless it has been imported from another system which supports more than one Announcements forum.

This forum is automatically created in a new course. By default, it is placed in the top of the central section and only teachers and only users with appropriate permissions (by default teachers) can post in it. The forum has forced subscription set by default.

Note: If your Moodle site has been upgraded to Moodle 3.1 from an earlier version of Moodle, then only newly created courses will have Announcements.

Please Help.

Thanks !

I didn't find the right solution from the internet.
